Waiting for PostgreSQL 18 – Allow json{b}_strip_nulls to remove null array elements

On 5th of March 2025, Andrew Dunstan committed patch: Allow json{b}_strip_nulls to remove null array elements   An additional paramater ("strip_in_arrays") is added to these functions.

JSON that just consists of a single null is not … Continue reading “Waiting for PostgreSQL 18 – Allow json{b}_strip_nulls to remove null array elements”

Waiting for PostgreSQL 18 – Allow parallel CREATE INDEX for GIN indexes

On 3rd of March 2025, Tomas Vondra committed patch: Allow parallel CREATE INDEX for GIN indexes   Allow using parallel workers to build a GIN index, similarly to BTREE and BRIN. For large tables this may result in significant speedup when the build is CPU-bound.   The work is divided so that each worker builds … Continue reading “Waiting for PostgreSQL 18 – Allow parallel CREATE INDEX for GIN indexes”

Waiting for PostgreSQL 18 – Allow EXPLAIN to indicate fractional rows.

On 21st of February 2025, Robert Haas committed patch: Allow EXPLAIN to indicate fractional rows.   When nloops > 1, we now display two digits after the decimal point, rather than none. This is important because what we print is actually planstate->instrument->ntuples / nloops, and sometimes what you want to know is planstate->instrument->ntuples. You can … Continue reading “Waiting for PostgreSQL 18 – Allow EXPLAIN to indicate fractional rows.”

Waiting for PostgreSQL 18 – Add cost-based vacuum delay time to progress views.

On 11st of February 2025, Nathan Bossart committed patch: Add cost-based vacuum delay time to progress views.   This commit adds the amount of time spent sleeping due to cost-based delay to the pg_stat_progress_vacuum and pg_stat_progress_analyze system views. A new configuration parameter named track_cost_delay_timing, which is off by default, controls whether this information is gathered. … Continue reading “Waiting for PostgreSQL 18 – Add cost-based vacuum delay time to progress views.”
