| 3 | +# Custom test for pg_stat_monitor extension |
| 4 | +# |
| 5 | +# IMPORTANT: This extension requires special handling because version 2.1 has different |
| 6 | +# schemas on PostgreSQL 15 vs 17, even though they share the same version number: |
| 7 | +# |
| 8 | +# - PG 15 (version 2.1): Uses older schema with `blk_read_time`, `blk_write_time` |
| 9 | +# - PG 17 (version 2.1): Uses newer schema with `shared_blk_read_time`, |
| 10 | +# `shared_blk_write_time`, `local_blk_read_time`, `local_blk_write_time`, plus |
| 11 | +# additional JIT columns (`jit_deform_count`, `jit_deform_time`, `stats_since`, |
| 12 | +# `minmax_stats_since`) |
| 13 | +# |
| 14 | +# During pg_upgrade from PG 15 to PG 17: |
| 15 | +# - The extension remains at version 2.1 |
| 16 | +# - No update script is generated (same version number) |
| 17 | +# - The schema stays as PG 15 (old schema) |
| 18 | +# - Fresh installs on PG 17 get the new schema |
| 19 | +# |
| 20 | +# This creates a conflict: the same expected output file (`z_17_pg_stat_monitor.out`) |
| 21 | +# is used for both scenarios, but they produce different schemas. |
| 22 | +# |
| 23 | +# Solution: Skip pg_regress after pg_upgrade when no update script is generated, |
| 24 | +# since the schema won't match the expected output for fresh PG 17 installs. |
| 25 | +# This still validates that: |
| 26 | +# - The extension version is correct after upgrade |
| 27 | +# - Fresh installs work correctly (tested by regular psql_17 check) |
| 28 | +# - Upgrade paths work correctly |
