moved everything into /trunk/ to create the standard svn layout, for use with tools that require this (eg. git-svn). IMPORTANT: do NOT do an `svn up`. instead, re-use your working copy's existing files with `svn switch` (http://svnbook.red-bean.com/en/1.6/svn.ref.svn.c.switch.html).
bugfix: schemas/pg_hba.conf: don't allow ident authentication for Unix socket connections, because this apparently prevents having normal, password-based connections ("md5"). note that just switching the order of the ident and md5 entries is not useful, because whichever authentication type comes second will be ignored completely. this problem was previously worked around by just not using Unix socket connections at all, and always specifying "localhost" as the host to force a hostname-based connection. this does not affect the postgres superuser, because they have their own ident line in pg_hba.conf.
schemas/pg_hba*.conf: removed trailing whitespace
schemas/pg_hba*.conf: allow the bien group to access all databases, including test (on the Mac). note that this does not grant access to the vegbank DB on vegbiendev, because that is owned by postgres.
Makefile mk_db, schemas/pg_hba*.conf: Added passwordless public_ user with access to just the database schema. Note that in PostgreSQL, only users with explicit GRANT permissions on a table can read data in that table, but all DB users with a login can view all table schemas.
schemas/: Synced pg_hba.conf and pg_hba.Mac.conf's bien entries, which adds phpPgAdmin support (template1 access) on the Mac and bien_read access on Linux
schemas/pg_hba.conf: Also grant the bien user access to template1, which is accessed by phpPgAdmin
schemas/pg_hba.conf: Fixed bug where also need an IPv6 bien entry with md5 authentication, because the IPv4 md5 authentication does not apply to "localhost", which is translated to the IPv6 address ::1
schemas/pg_hba.conf: Fixed bug where also need a local bien entry with md5 authentication, because the host-based md5 authentication applies only to literal IP addresses, not "localhost"
schemas/pg_hba.conf: Restrict all accesses to the server except the bien user accessing vegbien using ident or a password, and the postgres superuser logging in using ident
schemas/pg_hba.conf: Changed trust authentication back to ident/md5. Not sure how it got set to trust since I used md5 when enabling remote access to the DB for the bien user.
Added schemas/pg_hba.conf
