$Header$
* General
- Reset application name to "pgppol" when client disconnects(3.1. why
not use set command?) -> Done.
- Use reset_query_list to reset to "pgpool" for client disconnection
- Reset to client specified application name when reusing existing
connection.
- Allow to call pcp commands/show commands as a stored procedures of
PostgreSQL(3.1 SRAOSS)
- Allow client encoding conversion. This was possible in pgpool-I
- Avoid cross pgpool process deadlock situation. This is a long
standing problem since pgpool-II was born (pgpool-I avoids this by
setting timeout)
- If DISCARD ALL is specified in the reset_query_list and transaction
is not closed when client disconnects, automatically issue ABORT
before issuing DISCARD ALL
- Allow to specify queries issued when starting sessions
- Audit functionality?
- Make accept queue
- Graceful attaching a node
* Query handling
- Allow multi statement
- Enhance DROP DATABASE handling (not disconnect all idle connections)
* Replication
- Allow per table replication
- Allow per session level and query level load balancing
- More reliable way to replicate SEQUENCES
- Allow to replicate OIDs, XIDs
* Master/slave mode
- Allow to use more than 1 standbys(3.1)
* On line recovery
* Query cache
- Cache invalidation
- More effcient cache (memcache?)
* Log
- Mutiple log levels(3.1, but low priority)
- Multiple log destinations(3.1, but low priority)
* Parallel query
- Performance enhance for more complex queries
- Allow to handle transaction
- Allow to handle extended queries
- process alias in FROM clause
db=# select * from data1 as d1 inner join data2 as d2 on d1.id=d2.id;
ERROR: sql error
DETAIL: ERROR: missing FROM-clause entry for table "d1"

^
2008-03-11 10:28:17 LOG: pid 6186: statement: SELECT pool_parallel("SELECT d1.id, d1.aaaa, d1.bbbb, a.cccc FROM data1")
- process USING clause in JOIN
* pgpoolAdmin
- Allow to use double quotation in reset_query_list
- German messages
- Allow to run pgpoolAdmin on a host different from a host which
pgpool-II is running on(3.2?)
- Allow to stop PostgeSQL from pgpoolAdmin to make the on-line
recovery more convenient(pgpool_stop()?)
* Docs
- Write libpcp API docs
- French documentations(3.1)
- German documentations(3.1)
