I am using PostgresSQL 9.5.0. I have customized : https://github.com/michaelpq/pg_plugins/tree/master/decoder_raw to get result as json. It works fine. suddenly i getting below exception while consuming or peeking changes through that logical slot. Does postgres removed the rows needed for that slot?? Kindly help me to find the problem. db=# select * from pg_logical_slot_get_changes('lslot',NULL,1); ERROR: missing chunk number 0 for toast value 857563 in pg_toast_782254 CONTEXT: slot "lslot", output plugin "rep_slot", in the change callback, associated LSN 2E/3C26D6F0 select * from pg_class where relname like 'pg_toast_782254'; -[ RECORD 1 ]-------+---------------- relname | pg_toast_782254 relnamespace | 99 reltype | 782273 reloftype | 0 relowner | 10 relam | 0 relfilenode | 782272 reltablespace | 0 relpages | 464 reltuples | 2066 relallvisible | 464 reltoastrelid | 0 relhasindex | t relisshared | f relpersistence | p relkind | t relnatts | 3 relchecks | 0 relhasoids | f relhaspkey | t relhasrules | f relhastriggers | f relhassubclass | f relrowsecurity | f relforcerowsecurity | f relispopulated | t relreplident | n relfrozenxid | 1982173 relminmxid | 1 relacl | reloptions | Thanks In Advance. ----- sudalai -- View this message in context: http://postgresql.nabble.com/ERROR-missing-chunk-number-0-for-toast-value-while-using-logical-decoder-tp5909194.html Sent from the PostgreSQL - general mailing list archive at Nabble.com. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
