Am currently writing (or trying to at least) a postgresql driver for the 
koffice app kexi.

The driver requires that i subclass some kexi classes, one being a class that 
represents a field.

I know the SQL statement used to generate the result and for each field inthe 
result i create an object.  However, one property of the object is the table 
name for the field.  Other properties require that i know the table name, eg 
given the table and field names i can query the system catalogs to get things 
like contraints.

In the my_sql c library, the result (tuble) structure contains a filed 
structure that contains the table name that the particular field originated 
in, but libpq doesnt seem to have any similar kind of functionality (and i 
have looked a lot i think)

Has anyone any suggestions on how i can achieve getting the table name for a 
filed in a result without having to parse the sql statement (which i dont 
think wold be easy).
