I'm trying to install orafce extension on postgresql 10.1. I'm getting the next error : Could not load library "$libdir/orafce": ERROR: could not load library "MyPATH/orafce.so": MyPATH/orafce.so: undefined symbol: Float8GetDatum
When I run make install I dont get any errors. This is part of upgrade of postgreqsl 9.6.3 to 10.1. I got the error when I run pg_upgrade --check
Any idea what can I check ?
