Summary

Three issues found and fixed in 10-using-extensions.mdx after full re-verification on live PG 16.9 and PG 18.1 clusters:

  • TimescaleDB: Remove continuous aggregate and add_retention_policy examples — the bundled spilo image uses timescaledb.license=apache, making these Timescale-license features unavailable at runtime. Added a note explaining the limitation.
  • roaringbitmap: Fix example to use rb_build(ARRAY[...]) with literal values instead of selecting from a users table that was never created.
  • pglogical OpsRequest: Fix incomplete shared_preload_libraries value (was missing auto_explain, bg_mon, pgextwlist, pg_auth_mon, set_user, pg_stat_kcache, pg_duckdb); add SHOW shared_preload_libraries step before modifying to avoid silently dropping existing libraries.

Closes #249

  instead of selecting from a nonexistent users table.

- pglogical OpsRequest: fix incomplete shared_preload_libraries value (was
  missing auto_explain, bg_mon, pgextwlist, pg_auth_mon, set_user,
  pg_stat_kcache, pg_duckdb); add SHOW-first instruction to avoid accidentally
  dropping existing libraries.
