Re: What Are Last Steps Performed When PostgreSQL Starts?

Forgot about 'pg_ctl status'. That will work fine for my needs.

Ray Stell mentioned it would be helpful to see a description of all the
things that go on from start to finish, in general or course. I agree. It
helps to know the logic going on behind the scenes when things break. I had
a problem in August where PostgreSQL would not come up; I finally traced it
to broken links in the libraries, but it took a long time to find .... and
there were no error messages logged to help. Does this kind of information
exist anywhere?

I'm confused about whether you are talking about installation or server
startup. If installation, shouldn't your script just be waiting for the
subprocess to exit? As for server startup, the best procedure is the
one pg_ctl uses: try to make a connection, if fail, sleep a second or so
and try again.
