Dears,
Need you help with the below file manipulation. I want to split the file into 8 smaller files but without cutting/disturbing the entries (meaning every small file should start with a entry and end with an empty line).

start_transaction
START TRANSACTION(7) PostgreSQL 9.2.7 Documentation START TRANSACTION(7)NAME
START_TRANSACTION - start a transaction block
SYNOPSIS
START TRANSACTION [ transaction_mode [, ...] ]
where transaction_mode is one of:
ISOLATION LEVEL { SERIALIZABLE | REPEATABLE READ | READ COMMITTED | READ UNCOMMITTED }
READ WRITE | READ ONLY
[ NOT ] DEFERRABLE
DESCRIPTION
This command begins a new transaction block. If the isolation level, read/write mode, or deferrable mode is specified, the new transaction
has those characteristics, as if SET TRANSACTION (SET_TRANSACTION(7)) was executed. This is the same as the BEGIN(7) command.
PARAMETERS
Refer to SET TRANSACTION (SET_TRANSACTION(7)) for information on the meaning of the parameters to this statement.
COMPATIBILITY
In the standard, it is not necessary to issue START TRANSACTION to start a transaction block: any SQL command implicitly begins a block.
PostgreSQL's behavior can be seen as implicitly issuing a COMMIT after each command that does not follow START TRANSACTION (or BEGIN), and
it is therefore often called "autocommit". Other relational database systems might offer an autocommit feature as a convenience.
The DEFERRABLE transaction_mode is a PostgreSQL language extension.
The SQL standard requires commas between successive transaction_modes, but for historical reasons PostgreSQL allows the commas to be
omitted.
See also the compatibility section of SET TRANSACTION (SET_TRANSACTION(7)).
