Thank you to everyone who responded I have learned much about pgsql and 
am most grateful.
I did not have any pgsl databases to test on hence the failures.
After reading the responses and realizing that there was no database 
being created by Rails, went back to basics.
Rails generates a file database.yml. Tutorials instruct that one must 
have host: localhost in each of the test, def and prod configurations.
In a test this morning I left that line out and rake db:create worked as 
did rails new scaffold somename name:string.
This rather substantiates my contention that I have something very wrong 
with apache or it's config. More testing unfortunately!

Thanks also for the tips on grep [] and pgrep.
