Hello, there. I have a file that's a horrible, horrible mess. (Basically, it's an export from a firewall config.) The people who generated the file didn't think that putting a newline in the middle of a hostname would ever be a problem. It is.

BEGIN(7) SQL Commands BEGIN(7)
NAME
BEGIN - start a transaction block
SYNOPSIS
BEGIN [ WORK | TRANSACTION ]
INPUTS
WORK
TRANSACTION
Optional keywords. They have no effect.
OUTPUTS
BEGIN This signifies that a new transaction has been started.
WARNING: BEGIN: already a transaction in progress
This indicates that a transaction was already in progress. The current transaction is not affected.
DESCRIPTION
By default, PostgreSQL executes transactions in unchained mode (also known as ``autocommit'' in other database systems). In other words,
each user statement is executed in its own transaction and a commit is implicitly performed at the end of the statement (if execution was
successful, otherwise a rollback is done). BEGIN initiates a user transaction in chained mode, i.e., all user statements after BEGIN com-
mand will be executed in a single transaction until an explicit COMMIT [commit(7)] or ROLLBACK [rollback(7)]. Statements are executed more
quickly in chained mode, because transaction start/commit requires significant CPU and disk activity. Execution of multiple statements
inside a transaction is also useful to ensure consistency when changing several related tables: other clients will be unable to see the
intermediate states wherein not all the related updates have been done.
The default transaction isolation level in PostgreSQL is READ COMMITTED, wherein each query inside the transaction sees changes committed
before that query begins execution. So, you have to use SET TRANSACTION ISOLATION LEVEL SERIALIZABLE just after BEGIN if you need more rig-
orous transaction isolation. (Alternatively, you can change the default transaction isolation level; see the PostgreSQL Administrator's
Guide for details.) In SERIALIZABLE mode queries will see only changes committed before the entire transaction began (actually, before
execution of the first DML statement in the transaction).
Transactions have the standard ACID (atomic, consistent, isolatable, and durable) properties.
NOTES
START TRANSACTION [start_transaction(7)] has the same functionality as BEGIN.
Use COMMIT [commit(7)] or ROLLBACK [rollback(7)] to terminate a transaction.
Refer to LOCK [lock(7)] for further information about locking tables inside a transaction.
If you turn autocommit mode off, then BEGIN is not required: any SQL command automatically starts a transaction.
USAGE
To begin a user transaction:
BEGIN WORK;
COMPATIBILITY
SQL92
BEGIN is a PostgreSQL language extension. There is no explicit BEGIN command in SQL92; transaction initiation is always implicit and it
terminates either with a COMMIT or ROLLBACK statement.
Note: Many relational database systems offer an autocommit feature as a convenience.
Incidentally, the BEGIN keyword is used for a different purpose in embedded SQL. You are advised to be careful about the transaction seman-
tics when porting database applications.
SQL92 also requires SERIALIZABLE to be the default transaction isolation level.
