 dramforever | should have checked | 12:16:24 |

That's the only attribute available anyway, but yeah why does it have _unstable suffix then? | 13:08:48 |
| Sandro | In reply to @rick:matrix.ciphernetics.nl
There's a PR in flight to rename it because it is the only attribute name from me 😅 I think 3rd try or so | 13:08:59 |
 Rick (Mindavi) | Yeah, I'd like to go for it this time 😁 | 13:10:00 |

 hacker1024 | I am getting a lot of these messages from hydra-server and hydra-send-stats after upgrading nixos-unstable. Is there a manual step that needs to be done? I did not change my system stateVersion.
WARNING: database "hydra" has a collation version mismatch
DETAIL: The database was created using collation version 2.38, but the operating system provides version 2.39.
HINT: Rebuild all objects in this database that use the default collation and run ALTER DATABASE hydra REFRESH COLLATION VERSION, or build PostgreSQL with the right library version.

 K900 | It literally tells you what to do | 11:49:50 |
| hacker1024 | I am not familiar with SQL or SQL servers in general. Am I supposed to use some tool to open a PostgeSQL console? | 11:51:19 |
| hacker1024 | And I'm not sure what are keywords or placeholders in the given command | 11:51:53 |
| hacker1024 | Or if Hydra needs to be stopped during this process | 11:52:21 |
| Rick (Mindavi) | Hmm, maybe PostgreSQL updated? Normally this shouldn't happen, and nothing in the hydra schema changed | 13:50:17 |

 das_j | It happens when the glibc version of postgres changes | 06:48:10 |

| Sandro | sudo -u postgres psql and run the command | 12:14:17 |
| Rick (Mindavi) | Maybe something for the wiki | 17:48:25 |
|  noisersup joined the room. | 17:58:00 |
| Sandro | that's pretty much standard postgres knowledge | 18:25:42 |
 Alyssa Ross | not necessarily standard Hydra knowledge though | 18:26:29 |
| Rick (Mindavi) | I don't really feel qualified as a database admin but generally it goes fine for me, until I need to update major PostgreSQL databases | 19:41:54 |

| dramforever | til to even use the postgres user, i've been using hydra | 02:06:43 |
| dramforever | unrelatedly | 02:24:20 |
| dramforever | how do the hydra people, so to speak, feel about adding additional meta attributes to the db into the builds table? | 02:24:44 |
| dramforever | basically i'm trying to see if i can (we can?) work around this https://github.com/NixOS/nix/issues/2742 in hydra by adding like meta attributes | 02:27:33 |
| dramforever | so i'm imagining something like meta.requiredSystemFeatures that adds the features strictly when scheduling in hydra | 02:31:34 |

 vcunat | Hydra already has issues with the case where you change a (fixed-output) derivation while keeping the output hash. | 10:20:41 |
| vcunat | It will reuse the old build and with it the old derivation. | 10:21:18 |
| vcunat | Even if it was failed. | 10:22:08 |
