Subject: fix: don't use select as wait function if possible
X-Git-Tag: pool-3.2.0~104
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=ea350698605972d9f941701f3c0e7057c911face;p=thirdparty%2Fpsycopg.git

fix: don't use select as wait function if possible

select is marginally faster than others, but has the limitation of not
allowing FD > 1024, so it is not a good default.

If people need performance, they will use wait_c anyway, which is based
on poll, and doesn't have the limitation.
