On 18th of January, Stephen Frost committed patch:
Add ALTER TABLESPACE ... MOVE command This adds a 'MOVE' sub-command to ALTER TABLESPACE which allows moving sets of objects from one tablespace to another. This can be extremely handy and avoids a lot of error-prone scripting. ALTER TABLESPACE ... MOVE will only move objects the user owns, will notify the user if no objects were found, and can be used to move ALL objects or specific types of objects (TABLES, INDEXES, or MATERIALIZED VIEWS).
He followed it, with another commit:
Add CREATE TABLESPACE ... WITH ... Options Tablespaces have a few options which can be set on them to give PG hints as to how the tablespace behaves (perhaps it's faster for sequential scans, or better able to handle random access, etc). These options were only available through the ALTER TABLESPACE command. This adds the ability to set these options at CREATE TABLESPACE time, removing the need to do both a CREATE TABLESPACE and ALTER TABLESPACE to get the correct options set on the tablespace.
