Compat issue for using MySQL and LibPQ together on julia v1.11

[briederer]

I've recently stumbled upon a problem using julia v1.11 when trying to include the newest version of LibPQ and MySQL in the same package (more detailed description JuliaDatabases/LibPQ.jl#305).

I traced down the compat issue to the fixed compat of MariaDB_Connector_C_jll to v3.1.12 here.
Can this compat be lifted maybe?
