## AI overview

An overview of PostgreSQL 19's planned improvements, focusing on an in-core online table-rewrite capability that can reclaim bloated-table space while allowing reads and writes to continue. The article also discusses existing rewrite approaches, table bloat, dead tuples, and related extensions.

## Source excerpt

`VACUUM` reclaims dead-tuple space but doesn't shrink a table. PostgreSQL 19 Beta 2 adds an in-core online rewrite with REPACK (CONCURRENTLY), and much more.
