>From time to time I get this and similar errors in my Postgres log file:
< 2015-12-17 07:45:05.976 CST >ERROR: index "user_pictures_picture_dhash_idx" contains unexpected zero page at block 123780 < 2015-12-17 07:45:05.976 CST >HINT: Please REINDEX it. < 2015-12-17 07:45:05.976 CST >CONTEXT: PL/pgSQL function select_pictures_by_dhash(bigint,integer,integer) line 3 at RETURN QUERY < 2015-12-17 07:45:05.976 CST >STATEMENT: SELECT * FROM select_pictures_by_dhash(8559245352688506666,100,0) I have tried to recreate the index (create new index, drop the old one), but it doesnt help, the error comes back anyway. Also, its not there all the time, when I tried to rerun the statement from the logfile above a couple of hours later it worked fine without any error. The server is a read slave, set up with streaming replication. We run PostgreSQL 9.3.5. Is this anything I should be worried about, and if so, what can I do to fix it? Will it be fixed with a newer version of Postgres? Thanks! Victor
