Hello,
is it possible to use for example Postgresql database instead of Sqlite database? I've found that there is a Postgresql mapper (https://github.com/I2PC/scipion/blob/master/pyworkflow/mapper/postgresql.py), but it seems to be outdated and unmaintained. I also found that database layer does not seem to be well separated from other parts of the code (manipulation with Sqlite db files at various parts of code, ...), there is no abstraction, which is a terrible sw design and it hinders of simple addition of any new db implementation.

We would love to use a different type of database than Sqlite. Is there any way to use database like Postgresql, Mysql, ... instead of the Sqlite db? Are you planning to add possibility to use some other database?
