Hi Ramon,
If you want a VB like experience then:
1) use VB or
2) use REALbasic + pgSQL4RB which is a specialized solution for
PostgreSQL. You can find all about it by googling for pgSQL4RB.
RB (REALbasic) is very similar to VB and there are conversion tools
to go from VB to RB. But RB will also compile for Linux and Macintosh
(OS 9 and OS X).
