dblink_close(text cursorname [, bool fail_on_error]) returns text dblink_close(text connname, text cursorname [, bool fail_on_error]) returns text
Name of the connection to use; omit this parameter to use the unnamed connection.
The name of the cursor to close.
If true (the default when omitted) then an error thrown on the remote side of the connection causes an error to also be thrown locally. If false, the remote error is locally reported as a NOTICE, and the function's return value is set to ERROR.
If dblink_open
started an explicit transaction block,
and this is the last remaining open cursor in this connection,
dblink_close
will issue the matching COMMIT.
