Note: At present, this section is just taken from PostgreSQL documentation and is subject to revision for Postgres-XC.
The argument values supplied to a PL/Perl function's code are
simply the input arguments converted to text form (just as if they
had been displayed by a SELECT statement).
Conversely, the return
and return_next
commands will accept any string that is acceptable input format
for the function's declared return type.
