Re: Invalidation pg catalog cache in trigger functions

Sorry, I forgot to show version of PostgreSQL:

"Invalidation pg catalog cache in trigger functions"

was detected on "PostgreSQL 9.2.18 on x86_64-unknown-linux-gnu, compiled by gcc (Ubuntu 4.8.2-19ubuntu1) 4.8.2, 64-bit"

Also it can be reproduced on PostgreSQL 9.2.24

For newer versions it is not actual - PostgreSQL 9.3.20, 9.4.15, 9.4.12

But

Issue https://www.postgresql.org/message-id/20171030125345.1448.24038@wrigleys.postgresql.org  

"BUG #14879: Bug connected with table structure modification and trigger function query plan invalidation"

Is actual for PostgreSQL  9.2.24; 9.3.20; 9.4.12; 9.4.15

In this thread I propose to find out the cause of

Issue https://www.postgresql.org/message-id/20171030125345.1448.24038@wrigleys.postgresql.org

"BUG #14879: Bug connected with table structure modification and trigger function query plan invalidation"
