Hi all.
I'm working with Postgres 9.0 and wxWidgets.
I need to query the db about a field of a table.

The table T has a field varchar(50).

table: TAB0
customer: varchar(50)

How can I get the max size of the field?

The PQfsize function give me -1 because the field has dynamic size.

Can you help me?

Best regards
   MZ.
