Can you try to remove to bool.c commit and put it in another branch? I'd rather have this PR only containing the move from /meos/postgres to /postgres.

Of course we still need to wait until the branch stable-1.3 is created, but this can be committed as soon as it is done. Making changes to the code (e.g. adding bool.c) is something I want to do in a second step.

Absolutely ! It was planned like this. 
I just wanted to ensure that the current setting enables the future PRs that are in the pipeline, one per data type.
