wishlist: PQfsize

Hi all,

I would like to add the following item to the
wishlist:

currently the libpq-function PQfsize returns the
size in bytes of the field with the given field-
index. If the field is a variable-length field,
PQfsize returns -1.

In general as well as for some internal functionality
of the perl interface it would be useful, if PQfsize
would return the number of bytes even for variable-
length fields.

We have a new atttypmod field that holds the length for the column as
defined at table-creation time for char() and varchar(). Is that the
number you want?

for varchar() and also for the datatype text it would be
nice to know the actual length. If this is not possible,
then the length at creation time is still better than -1.

If you use binary cursors, you can use VARSIZE and VARDATA to see the
size and data for a string type.
