Lock in bdr

Hi,

I had a lot of problems configuring the DDR env with 2 nodes and now that
have it working, It easily gets locked.

My main problem is to get it unlocked. Anybody has experience with that?
When it´s locked and you have a record in bdr.bdr_global_locks with state
"acquired", which steps do you follow to get unlocked?

HINT: Node (6119460783368684166,1,16384) in the cluster is already
performing DDL

That one is because I add a PostGis extension in node1 in Pgadmin and it
added correctly and created the table spatial_ref_sys in node 1 but in node
2, tried to add the extension and got an error because the table does not
exists. I think that´s a bug because the table adds automatically when you
add the extension and it didn´t in node 2.

It´s a hard process to get it work because there is no much doc about it and
It´s driving me crazy...
