The standard test is to run "pg_dumpall", see if it finishes without error and if the dump can be restored without error. That won't detect any index corruption though. You could try: COPY (SELECT * FROM tab ORDER BY ...) TO 'file1'; SET enable_seqscan=off; COPY (SELECT * FROM tab ORDER BY ...) TO 'file2'; and see if "file1" and "file2" are identical. That would check the index used in the second COPY statement. I don't know, but maybe enabling checksums with the -k option of "initdb" would make such corruption more obvious.
