Operating system: Red Hat Linux 9.0
Description: problem with function return as integer[]
Details:

I compiled/linked a shared object against 7.4.5. My customer installed into
PostgreSQL 8.1beta1. My functions that return as integer[] give an empty
string (1 row) instead of the correct result (e.g., {{2,7}{4,5}}. Do I need
to recompile/link against 8.1 headers/objects?

FWIW, my 7.4.5 .so works in PostgreSQL 8.0.3.
