pg_field_type_oid — Returns the type ID (OID) for the corresponding field number
pg_field_type_oid() returns an integer containing the
OID of the base type of the given field
in the
given result
instance.
You can get more information about the field type by querying PostgreSQL's
pg_type
system table using the OID obtained with this function.
The PostgreSQL format_type() function will convert a
type OID into an SQL standard type name.
Зауваження:
If the field uses a PostgreSQL domain (rather than a basic type), it is the OID of the domain's underlying type that is returned, rather than the OID of the domain itself.

Примірник PgSql\Result, якого повертає одна з функцій pg_query(), pg_query_params() або pg_execute() (серед інших).
field
