force usage of pg.native via environment variable

[hoegaarden]

I want to force the usage of the native client without changing any code. This is especially useful when using modules which use node-postgresql.
With this patch node-postgres uses the native client when the environment variable NODE_PG_FORCE_NATIVE is set.

I think this is slightly hackish, but I can understand the use-case. The only thing missing is some sort of test. Maybe something like this:

process.env.NODE_PG_FORCE_NATIVE = true;
var pg = require('../../lib/pg');
//figure out some how this is the native binding
assert(pg instanceof require('../../lib/native/index));

That's psuedocode, but close to what the test should be I think.

Each test file runs in its own process so you wont affect 'global state' by modifying the environment variable there since the process is only alive while the test file runs. Just add the test under test/integration/client somewhere

Ok. I just fixed another bug (for 0.8.x). I'll add a testcase for my changes ...

[hoegaarden]

OK?

Sorry for the delay. I am at nodeconf and have been busy plus there is limited internet. I will merge this by end of weekend.
