varchar size

REGARDING varchar size
Given the results of a query using the perl interface to postgres, how can I
find the maximum length of the data returned for the varchar fields in the
query?
Is there something in the "results" buffer or can I query the system catalogs
for this information? If you need to query the system catalogs, what field
actually contains the maximum length of a varchar field? In other words, how
can I find what the field was defined as in the create table statement (e.g.,
...attribute1 varchar(12)...) using the system catalogs?
TIA,
Andy
