Only PPAS 8.3 uses, 'proargdefvals' for default arguments.
PG 8.4+ uses 'proargdefaults' for it and PPAS 8.4+adopted it from PG 8.4.

As per your suggestion, if we set the string for defCol only for particular
version of database server.
The variable - defCol will be empty for PG < 8.4 (not PPAS).
And, the query following the variable assignment will result in to an error
all the time for those servers.
