Subject: [Configurator-hackers] conf file converter
Message-ID: <200603091515.13283.josh@agliodbs.com>

Aurynn,

Here's the spec:

Supplied to the converter will be:

1 old conf file
1 new conf file
old version number
new version number

configuration matching table for names which have changed
(format to be determined) example:
7.4			8.0			8.1
sort_mem		work_mem	work_mem

The script should, based on the old conf file and the matching table, go 
through the new conf file one row at a time and set any of the variables 
which are set in the old file to the same values in the new conf file, and 
the same commented/uncommented status, ignoring values which were 
commented out in the old file.

But it should do it one line at a time so that the ordering and layout of 
the new file are preserved.

As a bonus, it would be nice to be able to handle special variable 
conversions, like if a 7.3 file has "tcp_ip = on" then the target 8.1 file 
should be set "listen_addresses='*'".   Howerver, this may prove more 
trouble than it's worth.
