The cause of the corruption may be a bug in a Postgis B-Tree operator
class. I reported a bug in the Geography type that could lead to
corrupt B-Tree indexes (not Geometry):
https://trac.osgeo.org/postgis/ticket/3841
Though I also see what could be a comparable bug in Geometry:
https://trac.osgeo.org/postgis/ticket/3777
These bugs are from about 3 years ago. If I'm right you should be able
to isolate the bug using amcheck.
