NAME
END - commit the current transaction SYNOPSIS
END [ WORK | TRANSACTION ] DESCRIPTION
END commits the current transaction. All changes made by the transaction become visible to others and are guaranteed to be durable if a crash occurs. This command is a PostgreSQL extension that is equivalent to COMMIT(7). PARAMETERS
