I would like to use SQL's log file to extract information from it.
This file can include four different types of instruction with the number of lines involved for each of them:
-> (1) "INSERT" instruction with the number of lines inserted
-> (2) "UPDATE" instruction with the number of lines updated
-> (3) "DELETE" instruction with the number of lines deleted
-> (4) "COLLECT STATISTICS" instruction with the number of lines involved.
The number of lines involved for "UPDATE" and "COLLECT STATISTICS" has exactly the same appearance in the log file:
-> for "COLLECT STATISTICS" instruction (check "Update completed" below)
-> for "UPDATE" instruction (check "Update completed" below)
The problem I face is the following: I am not interested by the number of lines involved in the "COLLECT STATISTICS" instruction and I am not able to recognize from the log file what kind of expression - "COLLECT STATISTICS" or "UPDATE" - produced "Update completed" in the log file !
So, I thought to cut off from the log file the multi-line record starting with "COLLECT STATISTICS" and ending with "changed." ... but I failed, I failed, I failed !
Thanks in advance for the attention you pay to my request and obviously, any suggestion over welcomed,

Hello all,
I am new to scripting and I have written a script that performs an Rsync on my NAS and then moves on to send me an email with the status etc. The problem is that I think Rsync is taking to long to complete and the IF statement is timing out, as it doesn't appear to move on.

ALTER FOREIGN TABLE(7) PostgreSQL 9.2.7 Documentation ALTER FOREIGN TABLE(7)NAME
ALTER_FOREIGN_TABLE - change the definition of a foreign table
SYNOPSIS
ALTER FOREIGN TABLE [ IF EXISTS ] name
action [, ... ]
ALTER FOREIGN TABLE [ IF EXISTS ] name
RENAME [ COLUMN ] column_name TO new_column_name
ALTER FOREIGN TABLE [ IF EXISTS ] name
RENAME TO new_name
ALTER FOREIGN TABLE [ IF EXISTS ] name
SET SCHEMA new_schema
where action is one of:
ADD [ COLUMN ] column_name data_type [ NULL | NOT NULL ]
DROP [ COLUMN ] [ IF EXISTS ] column_name [ RESTRICT | CASCADE ]
ALTER [ COLUMN ] column_name [ SET DATA ] TYPE data_type
ALTER [ COLUMN ] column_name { SET | DROP } NOT NULL
ALTER [ COLUMN ] column_name SET STATISTICS integer
ALTER [ COLUMN ] column_name SET ( attribute_option = value [, ... ] )
ALTER [ COLUMN ] column_name RESET ( attribute_option [, ... ] )
ALTER [ COLUMN ] column_name OPTIONS ( [ ADD | SET | DROP ] option ['value'] [, ... ])
OWNER TO new_owner
OPTIONS ( [ ADD | SET | DROP ] option ['value'] [, ... ])
DESCRIPTION
ALTER FOREIGN TABLE changes the definition of an existing foreign table. There are several subforms:
ADD COLUMN
This form adds a new column to the foreign table, using the same syntax as CREATE FOREIGN TABLE (CREATE_FOREIGN_TABLE(7)).
DROP COLUMN [ IF EXISTS ]
This form drops a column from a foreign table. You will need to say CASCADE if anything outside the table depends on the column; for
example, views. If IF EXISTS is specified and the column does not exist, no error is thrown. In this case a notice is issued instead.
IF EXISTS
Do not throw an error if the foreign table does not exist. A notice is issued in this case.
SET DATA TYPE
This form changes the type of a column of a foreign table.
SET/DROP NOT NULL
Mark a column as allowing, or not allowing, null values.
SET STATISTICS
This form sets the per-column statistics-gathering target for subsequent ANALYZE(7) operations. See the similar form of ALTER TABLE
(ALTER_TABLE(7)) for more details.
SET ( attribute_option = value [, ... ] ), RESET ( attribute_option [, ... ] )
This form sets or resets per-attribute options. See the similar form of ALTER TABLE (ALTER_TABLE(7)) for more details.
OWNER
This form changes the owner of the foreign table to the specified user.
RENAME
The RENAME forms change the name of a foreign table or the name of an individual column in a foreign table.
SET SCHEMA
This form moves the foreign table into another schema.
OPTIONS ( [ ADD | SET | DROP ] option ['value'] [, ... ] )
Change options for the foreign table or one of its columns. ADD, SET, and DROP specify the action to be performed. ADD is assumed if
no operation is explicitly specified. Duplicate option names are not allowed (although it's OK for a table option and a column option
to have the same name). Option names and values are also validated using the foreign data wrapper library.
All the actions except RENAME and SET SCHEMA can be combined into a list of multiple alterations to apply in parallel. For example, it is
possible to add several columns and/or alter the type of several columns in a single command.
You must own the table to use ALTER FOREIGN TABLE. To change the schema of a foreign table, you must also have CREATE privilege on the new
schema. To alter the owner, you must also be a direct or indirect member of the new owning role, and that role must have CREATE privilege
on the table's schema. (These restrictions enforce that altering the owner doesn't do anything you couldn't do by dropping and recreating
the table. However, a superuser can alter ownership of any table anyway.) To add a column or alter a column type, you must also have USAGE
privilege on the data type.
PARAMETERS
name
The name (possibly schema-qualified) of an existing foreign table to alter.
column_name
Name of a new or existing column.
new_column_name
New name for an existing column.
new_name
New name for the table.
data_type
Data type of the new column, or new data type for an existing column.
CASCADE
Automatically drop objects that depend on the dropped column (for example, views referencing the column).
RESTRICT
Refuse to drop the column if there are any dependent objects. This is the default behavior.
new_owner
The user name of the new owner of the table.
new_schema
The name of the schema to which the table will be moved.
NOTES
The key word COLUMN is noise and can be omitted.
Consistency with the foreign server is not checked when a column is added or removed with ADD COLUMN or DROP COLUMN, a NOT NULL constraint
is added, or a column type is changed with SET DATA TYPE. It is the user's responsibility to ensure that the table definition matches the
remote side.
Refer to CREATE FOREIGN TABLE (CREATE_FOREIGN_TABLE(7)) for a further description of valid parameters.
EXAMPLES
To mark a column as not-null:
ALTER FOREIGN TABLE distributors ALTER COLUMN street SET NOT NULL;
To change options of a foreign table:
ALTER FOREIGN TABLE myschema.distributors OPTIONS (ADD opt1 'value', SET opt2, 'value2', DROP opt3 'value3');
COMPATIBILITY
The forms ADD, DROP, and SET DATA TYPE conform with the SQL standard. The other forms are PostgreSQL extensions of the SQL standard. Also,
the ability to specify more than one manipulation in a single ALTER FOREIGN TABLE command is an extension.
ALTER FOREIGN TABLE DROP COLUMN can be used to drop the only column of a foreign table, leaving a zero-column table. This is an extension
of SQL, which disallows zero-column foreign tables.
