The original placement of this module in src/fe_utils/ is ill-considered,
because several src/common/ modules have dependencies on it, meaning that
libpgcommon and libpgfeutils now have mutual dependencies. That makes it
pointless to have distinct libraries at all. The intended design is that
libpgcommon is lower-level than libpgfeutils, so only dependencies from
the latter to the former are acceptable.
We already have the precedent that fe_memutils and a couple of other
modules in src/common/ are frontend-only, so it's not stretching anything
out of whack to treat logging.c as a frontend-only module in src/common/.
To the extent that such modules help provide a common frontend/backend
environment for the rest of common/ to use, it's a reasonable design.
(logging.c does not yet provide an ereport() emulation, but one can
dream.)
Hence, move these files over, and revert basically all of the build-system
changes made by commit cc8d41511. There are no places that need to grow
new dependencies on libpgcommon, further reinforcing the idea that this
is the right solution.

# Common rules for Native Language Support (NLS)

# If some subdirectory of the source tree wants to provide NLS, it
|
|
# needs to contain a file 'nls.mk' with the following make variable
|
|
# assignments:
|
|
#
|
|
# CATALOG_NAME -- name of the message catalog (xxx.po); probably
|
|
# name of the program
|
|
# AVAIL_LANGUAGES -- list of languages that are provided/supported
|
|
# GETTEXT_FILES -- list of source files that contain message strings
|
|
# GETTEXT_TRIGGERS -- (optional) list of functions that contain
|
|
# translatable strings
|
|
# GETTEXT_FLAGS -- (optional) list of gettext --flag arguments to mark
|
|
# function arguments that contain C format strings
|
|
# (functions must be listed in TRIGGERS and FLAGS)
|
|
#
|
|
# That's all, the rest is done here, if --enable-nls was specified.
|
|
#
|
|
# The only user-visible targets here are 'init-po', to make an initial
|
|
# "blank" catalog from program sources, and 'update-po', which is to
|
|
# be called if the messages in the program source have changed, in
|
|
# order to merge the changes into the existing .po files.
