pg_close — Closes a PostgreSQL connection
pg_close ([ resource $connection ] ) : bool
pg_close() closes the non-persistent connection to a PostgreSQL database associated with the given connection resource.
Note:
Using pg_close() is not usually necessary, as non-persistent open connections are automatically closed at the end of the script.
If there is open large object resource on the connection, do not close the connection before closing all large object resources.
connection
PostgreSQL database connection resource. When connection is not present, the default connection is used. The default connection is the last connection made by pg_connect() or pg_pconnect().
Returns true on success or false on failure.
