pg_connect() shows outdated example for "options"

[rgrellmann]

In "Example #1 Using pg_connect()" the last line shows the use of "options" in the connection string:
$dbconn5 = pg_connect("host=localhost options='--client_encoding=UTF8'");

In recent Versions of PHP/libpq/Postgres/pgbouncer this triggers the following Error:
pg_connect(): Unable to connect to PostgreSQL server: FATAL: unsupported options startup parameter: only '-c config=val' is allowed

Options can now be passed successfully only like this:
$dbconn5 = pg_connect("host=localhost options='-c client_encoding=UTF8 -c application_name=myapp'");

Please update the documentation.

pg_connect("host=localhost options='--client_encoding=UTF8'") works for me in PHP 8.4.4, libpq 16.4 and PostgreSQL 17.3.

What are your versions?
