Dear Gurus,

============================================================================
POSTGRESQL BUG REPORT TEMPLATE
============================================================================

Your name : Gabor Szucs
Your email address : surrano@mailbox.hu

System Configuration
---------------------
Architecture (example: Intel Pentium) : Intel Pentium 2

Operating System (example: Linux 2.0.26 ELF) : Debian "Woody" 2.4.21 Elf

PostgreSQL version (example: PostgreSQL-7.4): PostgreSQL-7.4

Compiler used (example: gcc 2.95.2) : gcc 2.95.4 20011002 (Debian
prerelease)

Please enter a FULL description of your problem:
------------------------------------------------

Abstract: setting unix_socket_directory in postgresql.conf seems to confuse
pg_ctl so that it starts postmaster but can't see it running so reports as
"failed"

Please describe a way to repeat the problem. Please try to provide a
concise reproducible example, if at all possible:
----------------------------------------------------------------------

Details:

1. Debian "Woody" Linux, appropriate postgresql (7.2.1) and php4 packages
installed.

2. I did my best to put 7.2.1 out of the way without uninstalling it, since
the php4-pgsql package depends on it.

3. Downloaded and unzipped postgresql-7.4 (also tried 7.4RC2 last weekend).
Configured to default port 5440 ("40" as in "(7.)4.0"). Compiled,
regress-tested, installed, initdb.

4. Configured postgresql.conf to use

unix_socket_directory = '/var/run/postgresql'

since Debian's php package requires socket files to be there.

5. Starting with

bin/pg_ctl -w -D data -l data/logfile

causes postmaster to start, but pg_ctl keeps sleeping and re-checking,
then gives up. However, postmaster runs, with socket files in the given
directory.

--------------------- cut here ---------------------

It seems my mail didn't hit the list, so I re-send it with the standard bug
template.

I know workarounds (the ugliest being "recompile php", or the simpler
"symlink the socket files from /tmp"). What I'm concerned is if I'm doing
something wrong, or is it an existent bug in Postgresql.

If needed, I can give detailed information (please specify) about my system,
or even try compiling and installing different versions with different
settings. I just don't have any ideas what to try and what not to so guide
me how to help you.

Re: unix_socket_directory vs pg_ctl?

Yep, bug. pg_ctl doesn't look at PGHOST to see if it is a path to the
socket files --- it only looks at PGPORT:

if "$PGPATH/psql" -p $PGPORT -l >/dev/null 2>&1

Added to TODO:

* Have pg_ctl look at PGHOST in case it is a socket directory

Dear Bruce,

Thanks for the confirmation. I'll stop searching the problem elsewhere then
:)

Yours,
