| 1) see re: increasing shmmax http://stackoverflow.com/a/10629164/1283020 | |
| 2) add to postgresql.conf: | |
| shared_preload_libraries = 'pg_stat_statements' # (change requires restart) | |
| 136 pg_stat_statements.max = 1000 | |
| 137 pg_stat_statements.track = all | |
| 3) restart postgres | |
| 4) check it out in psql |
