the MySQL developers actually messed things up with UTF8 and had to add 4-byte support afterwards(!) and even according to the MySQL documentation they describe possible issues when converting (UTF8 should just be UTF8. Convert UTF8 to UTF8? Come on!) from UTF8 to UTF8mb4. It sounded bad, and almost not true. So we decided to read about it ourselves, and as it turns out the IRC guys were right. PGSQL is a more advanced database in general and handles stuff more efficiently than MySQL/MariaDB, which also is proven in different benchmark testsSo we decided to give it a try, made a new branch, and started developing a PGSQL VM. We were kind of amazed since the end result was removing a lot if MariaDB lines and replace them with just a few PGSQL lines,Not only that, PGSQL is faster, it actually flies! Folders with many files loads faster, a gallery with many images loads faster,it also gives a feeling of being more secure. No need to save the root password in a separate file like we did with MariaDB, with PGSQL you authenticate with the UNIX user. Yeah you can do that with MariaDB as well, but again, it’s a feature, PGSQL does that by default. If you are convinced to change then great! The process is very easy and Nextcloud even have built in support for converting SQLite / MySQL / MariaDB to PGSQL (or the other way around) with the occ command. To make the leap smaller and easier for you we made a script that we used ourselves to make the change. Remember to test it on a clone of your server before you do it in production, you never know if and when stuff go wrong, and it’s better to be safe than sorry.
