Platform: "PostgreSQL 8.1.0 on i686-pc-mingw32, compiled by GCC gcc.exe (GCC) 3.4.2 (mingw-special)" To reproduce: 1. Make sure that postgres.conf file contains in first line: archive_command = 'copy "%p" "c:/arhiiv/%f"' 2. Edit postgres.conf file by adding # before this line #archive_command = 'copy "%p" "c:/arhiiv/%f"' 3. Run SELECT pg_reload_conf() in PgAdmin or in other client or use "Reload configuration" from XP Start menu. Log file contains received SIGHUP, reloading configuration files as expected. 4. Run SHOW archive_command Observed: archive_command value is copy "%p" "c:/arhiiv/%f" Expected: archive_command value is must be unset Before config file reload Postgres must set archive_command to unset.
