I finally figured out how to tackle the problem: 1. When I manually execute ANALYZE on the table the error remains:
[34938]-[192.168.67.81]-[DBeaver 7.3.2 - SQLEditor <Script-2.sql>]-[client backend]-[42501]-[postgres@fpdb] CONTEXT: SQL function "trigrams_vector" during inlining [34938]-[192.168.67.81]-[DBeaver 7.3.2 - SQLEditor <Script-2.sql>]-[client backend]-[42501]-[postgres@fpdb] STATEMENT: ANALYZE fpbackup.fp_vpn_data_2021w12 [31203]-[]-[]-[autovacuum worker]-[42501]-[@] ERROR: permission denied for schema dict at character 34 [31203]-[]-[]-[autovacuum worker]-[42501]-[@] QUERY: _to_string(dict.trigrams_array($1), ' ')::tsvector; This happens despite I run this query as superuser. But the hint from you allows me to manually reproduce error. 2. As I wrote before the owner of the table fpbackup.fp_vpn_data_2021w12 is "fpbkwriter" so I run the following query: GRANT USAGE ON SCHEMA dict TO fpbkwriter; and after that the problem has been solved. 3. The following queries do not affect the problem: GRANT EXECUTE ON ALL FUNCTIONS IN SCHEMA dict TO fpbkwriter; REVOKE EXECUTE ON ALL FUNCTIONS IN SCHEMA dict FROM fpbkwriter; -- Adrian, thank you very much for support. Your hints were very useful.
