ERROR: duplicate key violates unique
constraint "pg_class_oid_index"
I found a post earlier but wanted to post up my
info as the other persons did not look like the same type of error:
I tried to cluster the isbn_table
cluster isbn_index_code on
isbn_table;
ERROR: duplicate key violates unique constraint "pg_class_oid_index" The table looks like this
