Ok, that's one screen before the schreenshot I've posted. We can diff the plsql-subprograms-all*.{adp,tcl,xql} files and see what's different between yours and mine. For starter (that's from WNT machine), some stats:
[ ~/projects/oaks/packages/acs-api-browser/www ]
$ ls -l plsql-sub*-all*
-rw-r--r-- 1 a-popov None 431 Feb 17 23:10 plsql-subprograms-all-oracle.xql
-rw-r--r-- 1 a-popov None 386 Feb 17 23:10 plsql-subprograms-all-postgresql.xql
-rw-r--r-- 1 a-popov None 494 Mar 13 2001 plsql-subprograms-all.adp
-rw-r--r-- 1 a-popov None 772 Feb 17 23:10 plsql-subprograms-all.tcl
and -postgresql.xql file is:
<?xml version="1.0"?>
<queryset>
<rdbms><type>postgresql</type><version>7.1</version></rdbms>
<fullquery name="all_subprograms">
