Hello,

Is it possible to install parallel versions of Postgresql (from ports) on FreeBsd 8.1? I'd like to have 7.4 and 9.0 running on the same machine, listening to different ports.

Thanks!

Yes, you can use jail to host incompatible versions of same software.
On the other hand less waste of resources in dump_all-ing old databases and running latest with replication on both servers. Choice is yours.

PS jail gives different IP for jailed environment, not possible to pipe to other port on primary ip.

Yes use different ports and PGDATA environment variable to seperate the action.

Hmm, not quite sure I understand what earthman means...

So, I installed posgtres 9.0 from sources, with "--prefix=/usr/local/pgsql-9.0"

It works fine, but psql is looking for a server running on 5433:

psql: could not connect to server: Connection refused
	Is the server running locally and accepting
	connections on Unix domain socket "/tmp/.s.PGSQL.5433"?

Open in new window


Where is it getting that port? I can't find a .pgsqlrc anywhere...

So, is it possible with ports, without a jail?

No it is not possible, sorry.
(it is with forcing to override package dependencies with pkgtools, but it may or may not work afterwards, probably latest client can let old server work)
If you built something on your own ports may not work at all.

http://www.postgresql.org/docs/9.0/static/runtime-config-file-locations.html

"In a default installation, none of the above parameters are set explicitly. Instead, the data directory is specified by the -D command-line option or the PGDATA environment variable, and the configuration files are all found within the data directory.

If you wish to keep the configuration files elsewhere than the data directory, the postgres -D command-line option or PGDATA environment variable must point to the directory containing the configuration files, and the data_directory parameter must be set in postgresql.conf (or on the command line) to show where the data directory is actually located. Notice that data_directory overrides -D and PGDATA for the location of the data directory, but not for the location of the configuration files. "
