I think you meant parameters by "placeholders". For example:

INSERT INTO tbl (f1, f2, f3...) VALUES ($1, $2, $3, ...);
SELECT count(oid) FROM tbl WHERE field = $1;

AFAIC, PHP PostgreSQL API doesn't support any X_params() functions.
(Seems like stucked in escapeThatBuggyString() functions.)

Some of the functions I found that don't exist in both latest release
and CVS tree:

pg_prepare()
pg_query_params()
pg_field_type_oid()
pg_send_prepare()
pg_send_query_params()

(CVS checkout for ext/pgsql/pgsql.c:
http://cvs.php.net/co.php/php-src/ext/pgsql/pgsql.c?r=1.244.2.38)

Also, async query functions' interface is new as well. (Committed @
