Обсуждение: local_preload_libraries converts path to lowercase?
[TEST REPORT]
[Release]: 9.0beta2
[Test Type]: Application - configuration.
[Test]: Attempt to make use of the
local_preload_libraries option within postgresql.conf
[Platform]: SUN SPARC 4u Enterprise 450 Quad.
[Parameters]: attempt to use local_preload_libraries = /usr/local/lib/MyFavoriteLib.so. PG converts entire path to lowercase: /usr/local/lib/myfavoritelib.so.
[Failure]: Yes
[Results]: The Postgres binary converts the library name - in fact the entire pathname to the library - to lowercase. Attempt to connect to server using psql results in psql: FATAL: access to library "/usr/local/lib/myfavoritelib.so" is not allowed - even though permissions are 'permissive'.
[Comments]: (Whether our attempt to reference our preloaded library in this place is correct or not,) that the binary changes the directive to lower case seems odd.

Any idea if this is an issue on 8.4 as well?

OK, I'm passing this along to pgsql-bugs. I don't have the ability to
test it myself at the moment, and it's not a 9.0-specific bug.
