Translation updates for 7.4/7.5: postgres-ru.po.gz

Hello,

The attached file contains translation updates for the
postgres component. I addressed about 3 hundred
fuzzy and untranslated messages.

This file is primarily from the 7.4 branch but a large
chunk of the work should also apply to 7.5, so please
install it in the both, 7.4 and 7.5, branches.

$ msgfmt -cvf postgres-ru.po
581 translated messages, 1235 untranslated messages.

Thanks,
-s

PS: My installation of the gettext tools:

$ gettext --version
gettext (GNU gettext-runtime) 0.12.1

reported an error for the duplicate definition of the following message in
the .po file:

msgid "Try \"%s --help\" for more information.\n"

one for tcop/postres.c, the other one for postmaster/postmaster.c:

$ msgfmt -cvf postgres-ru.po
postgres-ru.po:6503: duplicate message definition
postgres-ru.po:5473: ...this is the location of the first definition
msgfmt: found 1 fatal error

So, I merged them into one. Let me know if this is undesired:

#: postmaster/postmaster.c:585
#: postmaster/postmaster.c:598
#: tcop/postgres.c:2565
#: tcop/postgres.c:2581
#, c-format
msgid "Try \"%s --help\" for more information.\n"
