This function is implemented in C, so there's no way to mimic it in SQL for older versions of PHP. But you can mimic some of the functionality by using a wrapper which keeps track of when you begin and commit/rollback transactions.

pg_transaction_status — Devuelve el estado actual de la transaccion del servidor

PGSQL_TRANSACTION_ACTIVE (a command is in progress),
PGSQL_TRANSACTION_INTRANS (idle, in a valid transaction block),
or PGSQL_TRANSACTION_INERROR (idle, in a failed transaction block).
PGSQL_TRANSACTION_UNKNOWN is reported if the connection is bad.
PGSQL_TRANSACTION_ACTIVE is reported only when a query
has been sent to the server and not yet completed.
