Guess what... In order to give you a reasonable answer to this question, we need the same kind of information I asked for (and never received) on the last thread you started:
Quote:
Which UNIX operating system are you using?
What shell are you using?
What is the format of your table?
Where is this table stored? If it is in a file, what type of file is it?
What have you tried to solve this problem on your own?
Is this a homework assignment?
Before you automate something, you typically do each of the steps manually and then automate those steps. So, in addition to the questions above:
- In what form is your list of table names?
- What commands would you run (please show us each command exactly as you would type it into your shell (in CODE tags)) to fetch all the data from one of your tables, to create a zip file for that table, and to store the data from that table in a directory on the server.

drop_table
DROP
TABLE(7) PostgreSQL 9.2.7 Documentation DROP TABLE(7)
NAME
DROP_TABLE - remove a table
SYNOPSIS
DROP TABLE [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]
DESCRIPTION
DROP TABLE removes tables from the database. Only the table owner, the schema owner, and superuser can drop a table. To empty a table of
rows without destroying the table, use DELETE(7) or TRUNCATE(7).
DROP TABLE always removes any indexes, rules, triggers, and constraints that exist for the target table. However, to drop a table that is
referenced by a view or a foreign-key constraint of another table, CASCADE must be specified. (CASCADE will remove a dependent view
entirely, but in the foreign-key case it will only remove the foreign-key constraint, not the other table entirely.)
PARAMETERS
IF EXISTS
Do not throw an error if the table does not exist. A notice is issued in this case.
name
The name (optionally schema-qualified) of the table to drop.
CASCADE
Automatically drop objects that depend on the table (such as views).
RESTRICT
Refuse to drop the table if any objects depend on it. This is the default.
EXAMPLES
To destroy two tables, films and distributors:
DROP TABLE films, distributors;
COMPATIBILITY
This command conforms to the SQL standard, except that the standard only allows one table to be dropped per command, and apart from the IF
EXISTS option, which is a PostgreSQL extension.
