I have not tried hitting the Assert(IsTransactionState() in
SearchCatCacheInternal. To do that, I need to figure out hitting
"incorrect binary data format in logical replication column" error in
either slot_modify_data or slot_store_data so that we will enter the
error callback slot_store_error_callback and then IsTransactionState()
should return false i.e. txn shouldn't be in TRANS_INPROGRESS. I'm not
sure how to do these things. I also looked at the commits 42c80c696e9
and ddfc9cb05 that added Assert(IsTransactionState()); in
SearchCatCacheInternal and RelationIdGetRelation for any relevant
tests or discussions, but I couldn't find anything.
Any further ideas in reproducing the issue?
