I've noticed a discrepancy in the return type for the gbt_cash_union function...
On fresh instances of postgres 9.6.11, where the btree_gist extension is newly created (version 1.2) yields a gbt_cash_union function with a return type of gbtreekey16 While instances that have been upgraded from 9.6.2 to 9.6.11, where the btree_gist was originally installed as 1.0 and then upgraded from 1.0 to 1.2 - that same function has a return type of gbtreekey8 I expect something is missing from the extension upgrade script to modify the return type. Is it safe/recommended to modify this function to return gbtreekey16? Perhaps safer still to drop the extension and recreate it? Thanks in advance. If this should be considered a bug, and there is a better place to report such - please advise. Tim
