Hideous "revdberr,invalid database type" returns in standalones

[Frank D. Engel, Jr.]

I believe I previously posted similar problems I am having with 2.5 and 
PostgreSQL.  Under Rev 2.2.1, using revdb to access PostgreSQL from 
standalones was working fine both on my X.3.5 development machine (with 
Rev and PostgreSQL installed) and on any Windows machine I tried 
(without Rev installed, either with or without PostgreSQL), as well as 
working fine as a stack in the IDE on my X.3.5 machine.

Now with 2.5, the Windows standalones still work fine, and the stack 
works fine in the IDE, but the MacOS X standalone does not work on my 
development machine, where Rev is installed.

I have yet to get a standalone working with RevDB/PostgreSQL from any 
of my *NIX boxes (haven't tried IRIX yet, but that machine is not 
currently hooked up, so it would take more time than it is presently 
worth -- maybe another time; I have tried Linux/IA32 and 
Solaris/SPARC).  This is true of 2.2.1 and 2.5.

I have not tried from another OS X machine, but can likely get access 
to one for testing later on.

Could these problems be related?
