Just to get an opinion, which is better:
could not open transaction log file "%s": %m
could not open control file "%s": %m
could not open data file "%s": %m
could not open temporary file "%s": %m
could not open whatever file "%s": %m
or just:
could not open file "%s": %m
It seems to me that by the time you get to a file error message of this
level, the higher-level purpose of the file is pretty irrelevant.
(Specific exceptions might exist.) Log analysis tools might also
prefer a uniform format.
Anyway, some consistency either way would be nice.
