tablespaces correctly, and is quite restricted on objects covered (only
tables and databases, but not tablespaces and indexes).

The attached patch contributes:

- database_size(name)
- relation_size(text)
These are the well-known functions, tablespace-aware.

- pg_tablespace_size(oid)
- pg_database_size(oid)
- pg_relation_size(oid)
Tablespace-aware implementations, used by the upper functions.
pg_relation_size will report sizes of indexes as well.

- pg_size_pretty(bigint)
Formatting of sizes, to display '146MB' instead of '152885668'

config file syntax errors so that it actually works reasonably well
(eg, points at the correct line).  Use palloc instead of malloc for
temporary storage to reduce code clutter.

We are still a long way from guaranteeing anything about using a

Fix TablespaceCreateDbspace() to be able to create a dummy directory
in place of a dropped tablespace's symlink.  This eliminates the open
problem of a PANIC during WAL replay when a replayed action attempts
to touch a file in a since-deleted tablespace.  It also makes for a
significant improvement in the usability of PITR replay.
