PostgreSQL: PGroonga 3.2.1 - Multilingual fast full text search

[NewsBot]

A new PostgreSQL blog post/announcement has been posted!

Hi,

PGroonga 3.2.1 has been released!

This release adds support for WAL resource manager!

With the WAL resource manager support, you can solve the following problems with the general WAL approach in PGroonga < 3.2.1:

• You need to remove old WAL manually to avoid unlimited storage usage
• You need to use additional mechanism to apply WAL in background
• You need to recover from a crash after PostgreSQL started

See also the following document how to use this feature: Streaming replication by WAL resource manager

Note that you need PostgreSQL 15 or later because this is based on custom WAL resource manager feature that is available since PostgreSQL 15.

If you're interesting in how to implement the WAL resource manager, see also the following blog post:
