Описание
string pg_field_type ( resource result, int field_number )
pg_field_type() returns a string containing the
base type name of the given field_number in the
given PostgreSQL result resource.
Замечание:
If the field uses a PostgreSQL domain (rather than a basic type), it is
the name of the domain's underlying type that is returned, rather than the
name of the domain itself.

This function used to be called pg_fieldtype().
