Does any one know how to properly extract a TEXT type blob (undefined char
length) in ecpg (Linux system)? We are converting our SQL from Informix to
PostGres. Informix had a specific struct defined and I believe handled the
dynamic memory allocation, but I cannot find any guidance on this issue for
PostGres. Anyone have any suggestions?
Thanks,
Tom

If you don't know how much memory to allocate for a column, you
could use a descriptor area and check RETURNED_OCTET_LENGTH. See
the "Using SQL Descriptor Areas" section in the ECPG documentation.
