As Tom mentioned, there's support for this feature in the protocol
level, but I don't know any API supports this yet. However, here's a
patch that adds Describe functionality for Prepared Statements and
Cursors to libpq:
http://archives.postgresql.org/pgsql-hackers/2006-06/msg01281.php
PHP supports it with the pg_field_type() function.
PHP uses libpq in the background to communicate with the server. How
can you wait PHP to support a feature that's not supported by libpq?
Furtheremore, pg_field_type() queries system catalogs to collect
information which is quite different than Describe functionality.
Really, I would have thought the PHP function would map directly to the
libpq PQftype() function. Although libpq returns the OID whereas the
PHP function returns the type. But I don't think that's what the
original user asked for given you need a ResultSet first.
It uses PQftype() to get the oid and then queries the pg_type table to
map the oid to the typname.
