Amazon RDS for PostgreSQL now supports PostgreSQL 19 Beta 4 in the Amazon RDS Database Preview Environment

Amazon RDS for PostgreSQL 19 Beta 4 Available

Starting today, Amazon RDS for PostgreSQL 19 Beta 4 is available in the Amazon RDS Database Preview Environment, allowing you to evaluate the pre-release of PostgreSQL 19 on Amazon RDS for PostgreSQL.

PostgreSQL 19 Beta 4 refines the query performance and autovacuum management capabilities introduced in earlier releases and includes bug fixes and stability improvements since Beta 3. Fixes include:

• pg_stat_autovacuum_scores view reporting for TOAST tables
• Corrected freeze-score scaling to tune autovacuum prioritization effectively
• Parallel autovacuum now shares a rebalanced cost limit across its workers to keep maintenance on large tables within your configured limits

Refer to the PostgreSQL community announcement for more details.

What to do

• Use the PostgreSQL dump and load functionality to import or export your databases from the Preview Environment
