It sounds like you envision tablespaces (or at least the default tablespace)
as being above databases in some contexts. Reducing other tablespaces
to mere subdirectories under the 'base' directory for a database sounds
like a practical implementation measure.

I presume that the 'global' directory is for stuff that is not specific
to any one database within a database cluster. If so, there is an
inconsistency in the current directory structure in that SOME global
information is in the main /usr/local/pgsql/data directory (or equivalent)
while other global information is in the global subdirectory.

Being able to zap a database with one or more 'rm -rf' commands assumes
that there will be files from just ONE database permitted in any given
tablespace, and ONLY files from that database. The former is probably
a good thing to require and enforce, the latter is unenforcable but
probably still advisable.

Is this doable within the time frame for the 7.4 feature freeze?
