TODO list for PostgreSQL

========================

Current maintainer: Bruce Momjian (pgman@candle.pha.pa.us)

The most recent version of this document can be viewed at the PostgreSQL web

site, http://www.PostgreSQL.org.

* Force archiving of partially-full WAL files when pg_stop_backup() is

called or the server is stopped

* Create dump tool for write-ahead logs for use in determining

transaction id for point-in-time recovery

* Set proper permissions on non-system schemas during db creation

* COPY

o Allow COPY to report error lines and continue

This requires the use of a savepoint before each COPY line is

processed, with ROLLBACK on COPY failure.

* CURSOR

o Allow UPDATE/DELETE WHERE CURRENT OF cursor

This requires using the row ctid to map cursor rows back to the

original heap row. This become more complicated if WITH HOLD cursors

are to be supported because WITH HOLD cursors have a copy of the row

o Allow INSERT/UPDATE of the system-generated oid value for a row

o Allow INSERT INTO tab (col1, ..) VALUES (val1, ..), (val2, ..)

o Allow INSERT/UPDATE ... RETURNING new.col or old.col

This is useful for returning the auto-generated key for an INSERT.

One complication is how to handle rules that run as part of

the insert.

to clients

* Allow queries across databases or servers with transaction

semantics

Right now contrib/dblink can be used to issue such queries except it

does not have locking or transaction semantics. Two-phase commit is

needed to enable transaction semantics.
