Your name : Rudolf Lippan
Your email address : rlippan(at)remotelinux(dot)com

System Configuration
---------------------
Architecture (example: Intel Pentium) : PII-400x4

Operating System (example: Linux 2.0.26 ELF) : 2.4.19-gentoo-r9

PostgreSQL version (example: PostgreSQL-7.3): PostgreSQL-7.3

Compiler used (example: gcc 2.95.2) : gcc 2.95.3

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

initdb (postmaster) segfaults. It seems that if I don't set the system's
timezone, postmaster does a li'le fandango on core. Pg 7.2.3 work fine.

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

postgres(at)war PGDATA $ date
Sat Dec 14 02:12:00 Local time zone must be set--see zic manual page 2002

And run initdb. Here is output from both runs of initdb:

postgres(at)war PGDATA $ ../pgsql7.3/bin/initdb
The files belonging to this database system will be owned by user
"postgres".
This user must also own the server process.

The database cluster will be initialized with locale C.

initdb failed.
Removing /usr/local/PGDATA/pgsql7.3.

==============
postgres(at)war PGDATA $ TZ=EST ../pgsql7.3/bin/initdb
The files belonging to this database system will be owned by user
"postgres".
This user must also own the server process.

The database cluster will be initialized with locale C.

Success. You can now start the database server using:

../pgsql7.3/bin/postmaster -D /usr/local/PGDATA/pgsql7.3
or
../pgsql7.3/bin/pg_ctl -D /usr/local/PGDATA/pgsql7.3 -l logfile start
