Package: postgresql
Version: 7.4.7-6sarge1
The init script for PostgreSQL ignores the environment options in
/etc/postgresql/postgresql.env.
This is an issue because I want to specify alternate database storage
locations (in addition to the default). So I add the following line to
/etc/postgresql/postgresql.env:
PGDATA2=/data-ext/postgres
That works fine for the frontend programs, which read
/etc/postgresql/postgresql.env. However, the init script has no
facility for setting environment variables besides editing the init
script itself. This is evident when I go to create the database using psql:
[EMAIL PROTECTED]:~$ createdb -D 'PGDATA2' alpha
createdb: database creation failed: ERROR: postmaster environment
variable "PGDATA2" not found
I propose the following line near the top of the init script:
. /etc/postgresql/postgresql.env
This sources the environment file so the daemon and the frontend
programs have the same relavent environment variables.
