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. -- Peter Geoghegan
