I am writing scripts to create a database that I want to run in my development, testing, and production environments. That means I need to be able to do something like

IF <condition>
  CREATE TABLESPACE foo LOCATION E'C:\database';
ELSE
  CREATE TABLESPACE foo LOCATION E'Z:\database';

I can't seem to find a way to do this, for two reasons:
1) I can't do IF statements unless I create a PL/PGSQL function. And a PL/PGSQL function cannot issue a CREATE TABLESPACE command.

Try constructing a string containing the command and using EXECUTE from plpgsql.

If you can't get that to work, you need to move the IF outside the database. You might do this with psql's variable interpolation (careful with the quoting) or a judicious mix of make/grep/sed/awk/perl etc.

Hmm - just noticed you're on Windows, so Perl etc won't be installed by default. I just install perl and/or cygwin, but presumably you have your own alternatives. I'm curious - what do you use for this sort of general utility & text-file mangling as a Windows developer?
