* Fix to STORE TRIGGER - store trigger was running against all nodes
upon subscription
* Portability changes to some tools/ scripts, fixing some
"bash-isms"
* Fix to switch statement in slonik.c; unknown how it broke
* Fix memory leak
- Fix typo in configure-replication.sh (missing CR)
- Per bug 35, search the Slony share dir for scripts
before falling back to the PG share dir on 8.0+
- Change test framework to write out the test name into
$TEMPDIR/TestName
- Patch that seems to resolve a race condition with
ACCEPT_SET
- Fix bug 49 - mishandling by slony_logshipper of quotes &
backslashes.
- Fix bug 50 - slony_logshipper had a variable access *after*
memory was freed
Changes 1.2.13:
- Fixed problem with compatibility with PostgreSQL 8.3; function
typenameTypeId() has 3 arguments as of 8.3.
- Added in logic to ensure that max number of SYNCs grouped together is
actually constrained by config parameter sync_group_maxsize.
- Fix to show_slony_configuration - point to proper directory where
slon/slonik are actually installed.
- Fix to slonik Makefile + slonik.c - Change slonik build to query
Postgres for the share directory at runtime - per Dave Page
- Removed spurious NOTIFY on "_%s_Confirm"; this is no longer needed
- Fixed problem with DDL SCRIPT parser where C-style comments were
not being processed properly
- Added stored functions and documentation for adding empty tables
(notably *partitions*) to replication. Note these functions
do no work when not specifically requested.
- Added a fairly substantial partitioning test to exercise the
new stored functions above.
- Backport "listen path" generator function from CVS HEAD (2.0) to
1.2 branch.
- Fixed a problem with "EXECUTE SCRIPT" (introduced in remote_worker.c
version 1.124.2.13) where moving the relevant code into a subroutine
at the end led to losing the "BEGIN; SET TRANSACTION ISOLATION LEVEL
SERIALIZABLE;" query that needs to be the first thing run...
- Fixing the archive sequence generations (in log shipping). All
non-SYNC events must start the local transaction before creating the
archive as well, so that the lock on the archive counter table
serializes archive creation.
- Fixed logging done in local_listener.c - various places, there was
no '\n' in some cases, which would lead to entries being folded
together.
- Fix launch_slons.sh - was not stripping quotes from PID file name
- Error handling for "ERROR: could not serialize access due to
concurrent update"
- Fixes to slonik_build_env script - it wasn't properly handling
cases where there was just 1 table or 1 sequence, and had a
problem with the -schema option - thanks, Bernd Helmle
It has a support for newer PostgreSQL versions, also various
improvements and bugfixes. Details could be found in the
RELEASE-1.2.{0-9} files of the source package.

- A major revision of memory management to limit memory usage by slon
daemons.
- Log switching: periodically
- pg_listener is now used dramatically less than it used to be, which
diminishes the number of dead tuples you will find in this table.
- DDL scripts are broken into individual statements
- Slony-I tables are now marked "WITHOUT OIDS" so that they do not
consume OIDS.
- When possible (based on log switching functionality), partial
indexes on sl_log_1 and sl_log_2 are created on a per-origin-node
basis.

and failover.
The big picture for the development of Slony-I is a master-slave system that
includes all features and capabilities needed to replicate large databases to
a reasonably limited number of slave systems.
Slony-I is a system for data centers and backup sites, where the normal mode
of operation is that all nodes are available
