The commit 04eee1fa9ee80dabf7 of this series causes a self-deadlock in the

same lockid.
CREATE INDEX planet_osm_ways_nodes ON planet_osm_ways USING gin (nodes)

It happens pretty reliably using osm2pgsql.
I will try to come up with a simple reproducible demonstration, and stack
trace, over the weekend.
Whatever the problem, it seems to have been fixed in ce5326eed386959aa,
"More GIN refactoring".
That's good, I guess :-). Thanks for the testing. Did you import the
full planet.osm? I tried with a subset containing just Finland, but
didn't see any problems.
