Remove IndexInfo.ii_OpclassOptions field
It is unnecessary to include this field in IndexInfo. It is only usedby DDL code, not during execution. It is really only used to passlocal information around between functions in index.c and indexcmds.c,for which it is clearer to use local variables, like in similar cases.Discussion:https://www.postgresql.org/message-id/flat/f84640e3-00d3-5abd-3f41-e6a19d33c40b@eisentraut.org
