[dx689]

Description

Hi everyone!
I use function pg_copy_from and encountered with missing parameter which describing escape char.
I need new parameter in pg_copy_from and pg_copy_to functions. Please, anybody, adding them to php-src/ext/pgsql/pgsql.c and (https://github.com/php/php-src/blob/master/ext/pgsql/pgsql.c#L3070)
Described PG parameter is here - https://postgrespro.ru/docs/postgresql/11/sql-copy, named as ESCAPE.

@devnexen is this something that should be added?
