@zmc @djgalloway guys, review please?

[tchaikov]

why? the newer the merrier?

[kshtsk]

This current version does not work for me on openSUSE:

     command: /home/kyr/kshtsk/paddles/v/bin/python2 -c 'import sys, setuptools, tokenize; sys.argv[0] = '"'"'/tmp/pip-install-4O1gZM/psycopg2/setup.py'"'"'; __file__='"'"'/tmp/pip-install-4O1gZM/psycopg2/setup.py'"'"';f=getattr(tokenize, '"'"'open'"'"', open)(__file__);code=f.read().replace('"'"'\r\n'"'"', '"'"'\n'"'"');f.close();exec(compile(code, __file__, '"'"'exec'"'"'))' egg_info --egg-base pip-egg-info

    or with the pg_config option in 'setup.cfg'.

The newer version does not need pg_config at all. Also even if install the devel package of postgresql where the pg_config resides, the 2.6.1 fails with error:

     command: /home/kyr/kshtsk/paddles/v/bin/python2 -c 'import sys, setuptools, tokenize; sys.argv[0] = '"'"'/tmp/pip-install-dUp6lS/psycopg2/setup.py'"'"'; __file__='"'"'/tmp/pip-install-dUp6lS/psycopg2/setup.py'"'"';f=getattr(tokenize, '"'"'open'"'"', open)(__file__);code=f.read().replace('"'"'\r\n'"'"', '"'"'\n'"'"');f.close();exec(compile(code, __file__, '"'"'exec'"'"'))' egg_info --egg-base pip-egg-info

i think it still needs pg_config. see http://initd.org/psycopg/docs/install.html#install-from-source

I can agree, but this is not required when installing not from the source code... in the newer version I guess they fixed this issue. As I said, it can not be installed even after I install the devel package with pg_config. The newer version works fine for me... Paddles is deployed and works with postgresql without problems.

[tchaikov]

could you update the commit message to explain why we want to bump the required psycopg2 version?

postresql: update dependency

is not accurate and is misleading.

i think a better one is something like

requirements.txt: bump up psycopg2

psycopg2 v2.6.1 does not support postresql 10
see psycopg/psycopg2#489

[tchaikov]

also, any reason not using the latest stable, say, 2.8.3?

[kshtsk]

I took the first working version for me at that time, and it tested for more than 2 months.
So the only reason of not taking 2.8.3 is that I haven't tested it at all.

DONE

@tchaikov oh... sorry, this patch is dated by 7 May, so it has been working for me for 5 months.
