orafce - orafce: Change argument types of concat() from anyelement to

Log Message:
-----------
Change argument types of concat() from anyelement to anynoarray
to replace || operators easily, suggested by Ingmar Brouns.

Also, split the install script for each postgres version
to avoid errors during installation.

Regression test now works on 9.0 and 8.4 cleanly,
but 8.3 or earlier versions requires more works...
