Thank you for rebasing.
I have noticed that when I create a table or an index on this table, there is no information about the table or index in pg_stat_vacuum_tables and pg_stat_vacuum_indexes until we perform a VACUUM.
Example:
CREATE TABLE t (i INT, j INT);
INSERT INTO t SELECT i/10, i/100 FROM GENERATE_SERIES(1,1000000) i;
SELECT * FROM pg_stat_vacuum_tables WHERE relname = 't';
....
(0 rows)
CREATE INDEX ON t (i);
SELECT * FROM pg_stat_vacuum_indexes WHERE relname = 't_i_idx';
...
(0 rows)
I can see the entries after running VACUUM or executing autovacuum. or when autovacuum is executed. I would suggest adding a line about the relation even if it has not yet been processed by vacuum. Interestingly, this issue does not occur with pg_stat_vacuum_database:
CREATE DATABASE example_db;
SELECT * FROM pg_stat_vacuum_database WHERE dbname = 'example_db';
dboid | dbname | ...
... | example_db | ...
(1 row)
BTW, I recommend renaming the view pg_stat_vacuum_database to pg_stat_vacuum_databaseS for consistency with pg_stat_vacuum_tables and pg_stat_vacuum_indexes
