Fix segmentation fault when error query and Sync message are sent in native replication mode. (bug 434) (Takuma Hoshiai)

In native replication mode, segmentation fault occurs when Sync messages is sent just after a query error.

Fix syntax error when queries including time functions and IN (SELECT ...) in WHERE clause in native replication mode. (bug 433) (Bo Peng)

In native replication mode, queries including time functions (e.g. now(), CURRENT_TIMESTAMP etc.) are rewritten to a timestamp constant value. However, Pgpool-II doesn't support queries including time functions and IN (SELECT ...) in WHERE clause.

Fix occasional less data returned to frontend with extended protocol. (bug432) (Tatsuo Ishii)

The idea for fix is, use pending message data list. It records messages from frontend, and it is expected that we will receive same number of messages.

Initial patch is created by Yugo Nagata and fixed by Tatsuo Ishii.

Fix memory leak in trigger_failover_command(). (Tatsuo Ishii)

Fix memory leak when query cache enabled in streaming replication mode + extended query case. (Tatsuo Ishii)

Fix memory leak when memory_cache_enabled = on and write SQLs are sent. (Bo Peng)

In a explicit transaction, the SELECT results are cached in temporary buffer. If a write SQL is sent which modifies the table, the temporary buffer should be reset.

Fix occasional failure in regression 065.bug152. (Tatsuo Ishii)

Test: Add EXECUTE/DEALLOCATE regression test. (Takuma Hoshiai)

Add missing pgpool_recovery--1.0--1.1.sql file to update pgpool_recovery() function version to 1.1. (Bo Peng)

Fix kind mismatch error when DEALLOCATE statement is issued. (Bo Peng)

PREPARE should be add to pool_add_sent_message, so that EXECUTE and DEALLOCATE can be sent to the same node as PREPARE.

See [pgpool-general: 6226] for more details.

Do not update pool_passwd if the password length is incorrect. (bug 419) (Takuma Hoshiai, Tatsuo Ishii)

For Pgpool-II 3.7 or before, the password stored in pool_passwd is MD5 password only. So check the correctness of pool_passwd by scanning entire file.

Test: Update clean.sh which clean up regression test results. (Bo Peng)

Fix segfault when node 0 is in down status in case of both health check and failover_on_backend_error are disabled. (Tatsuo Ishii)
