2.4.0

2.3.0

Release 2.2.0

2021-06-15T20:55:12Z

Release 2.2.0

TL;DR Since version 2.2 we use a different algorithm for tracking changed pages. Thus, data recorded in the `ptrack.map` using pre 2.2 versions of `ptrack` is incompatible with newer versions. After extension upgrade and server restart old `ptrack.map` will be discarded with `WARNING` and initialized from the scratch.

* `ptrack` now uses two slots to record page change information. It
helps significantly reduce number of false positives with the same
`ptrack.map_size`. See #5 for details. Many thanks to @funny-falcon for
ideas, theory and review!
* `ptrack_get_pagemapset()` now also displays a number of changed blocks
per file.
* Added `ptrack_get_change_stat(start_lsn pg_lsn)` that can desplay statistic
of changes (number of files, pages and size in MB) since specified `start_lsn`.

Release 2.1.2

2021-03-31T11:17:43Z

Release 2.1.2

* Fix int32 overflow when doing a `ptrack` checkpoint with
`ptrack.map_size` > 16 GB.
* Adjust `ptrack` checkpoint buffer for a ~20% better performance.

Release 2.1.1

2021-01-19T15:28:42Z

Release 2.1.1

* PostgreSQL 11 and 13 support. Thanks to @alubennikova.
* Fixed an int32 overflow issue, when one was unable to set
ptrack.map_size to 2 GB and above. New limit is 32 GB.

Release 2.1.0

2020-06-06T11:13:48Z

Release 2.1.0

Both `ptrack` engine and public SQL API are now inside extension. Only
certain required hooks have been left as a PostgreSQL core patch.

Also many things have changed since 2.0.0:

* Fixed many compatibility bugs: alignment issues with atomics usage on Win32,
with atomics simulation via spinlocks.
* Added versioning into the `ptrack` map.
* Added automated standalone testing with `pg_probackup` via travis-ci in
different modes, including a 'legacy' mode, i.e. with `EXEC_BACKEND`
and `--disable-atomics`.
* Removed `pg_ptrack_get_block`.

Release 2.0.0

2020-05-26T15:26:05Z

Ptrack is a fast block-level incremental backup engine for PostgreSQL.

Currently `ptrack` codebase is split approximately 50%/50% between
PostgreSQL core patch and extension. All public SQL API methods are
placed in the `ptrack` extension, while the main engine is still in core.
