This is a reminder of today's RFC discussion about MediaWiki's database schema for PostgreSQL. Tim proposes to make it more similar to our MySQL schema, to reduce maintenance overhead and breakage https://phabricator.wikimedia.org/T164898.
Rationale: The inconsistencies between the MySQL and PostgreSQL schemas cause a constant maintenance burden. PostgreSQL support is frequently broken in master. The PostgreSQL schema is certainly better than the MySQL one, if analyzed in isolation, but the advantages to PostgreSQL users of having an improved schema are more than outweighed by the disadvantages of inconsistency with the remainder of the installed MediaWiki user base.
The discussion will take place on the #wikimedia-office channel on Freenode, at 21:00 UTC (2pm PDT, 23:00 CEST).
