Just thinking if its worth it to ad a how to mysql and a how to postgress to gitea?

[guillep2k]

LGTM once the utf8 issue is properly cleared.

[lunny]

And I think you could also mention, once you chose to use utf8mb4, it may report the index size is too large and you may want to

SET GLOBAL innodb_file_format=Barracuda;
SET GLOBAL innodb_file_per_table=ON;
SET GLOBAL innodb_large_prefix=1;

[bagasme]

@lunny Should your suggestion (SET GLOBALs) be applied before or after database creation?

[lunny]

@bagasme before database creation.

[bagasme]

@lunny I think those SET GLOBALs aren't needed for MariaDB 10.2.2 and later because those already been set as default.

[silverwind]

For MySQL, those three settings are also the default since 5.7 I think. Assuming new installations use at least that version, I think it's better to omit them. utf8mb4 is default since 8.0.
