Add support for installing from default debian repositories for ARM targets

[axos88]

This PR adds support for

• installing from default debian repositories, rather than the postgresql repos
• backward compatibility down to 9.1

Postgresql repositories do NOT have binaries for ARM architectures.
I need to use the packages supplied by debian themselves for this. The debian repos have only 9.1 installed.

Hi @axos88,
I've been testing this PR on Debian 7.7, and when i try to start postgresql (or the Restart PostgreSQL task), i get this:

Starting PostgreSQL 9.1 database server: mainThe PostgreSQL server failed to start. Please check the log output. ... failed!

Do you have the same problem?

Regards.

it was working on debian 7.5 for me. What's the actual error you get? (int he logs)

Hi @axos88,
Using Debian repo and PostgreSQL 9.1, i've got:

 PST LOG:  database system was shut down at 2014-12-30 02:42:43 PST
 PST LOG:  database system is ready to accept connections
 PST LOG:  autovacuum launcher started
 PST LOG:  incomplete startup packet
 PST LOG:  received fast shutdown request
 PST LOG:  aborting any active transactions
 PST LOG:  autovacuum launcher shutting down
 PST LOG:  shutting down
 PST LOG:  database system is shut down

I've got another issue, using PostgreSQL repo and 9.1 (seems not related imho).

Thx!

Ok, I tested and it was a problem with shared_buffers value, which was too high. Not really related to this PR.

Sry.

[guillaumededrie]

Hum, seems we have to be careful: http://leopard.in.ua/2013/09/05/postgresql-sessting-shared-memory/ (the PostgreSQL 9.3 section).

As Ansible handle mutliple booleans forms (True/yes/…) you should remove the == True part.

[axos88]

Nice catch.

[guillaumededrie]

@axos88, sry i missed this one …

What's the status on this? I'm short on time to do a proper review on a different architectures.

Sorry for the delay as well. Same reason.

👎 now that #63 is merged, the part regarding the choice of repo is obsolete, and #65 would a be cleaner way to disable the apt tasks if you want to.

By the way, I don't see what in this PR is ARM or Debian specific...
