Please note:
I tried it also with Postgres 15.6 and the behavior is the same I'm running inside docker. I do not know if it matters… Hi All, I think I hit a bug in logical replication in version 15.2. I sync two tables of size 305MB but pg_stat_progress_copy shows that 5GB as bytes_processed and the sync takes forever. Is this a bug? If so, what can I do with this scenario? Thanks Create a dummy table
CREATE TABLE example_table ( id SERIAL PRIMARY KEY, binary_data BYTEA ); Create a function that inserts a row of few MB into the table CREATE OR REPLACE FUNCTION generate_large_data() RETURNS BYTEA AS $$ DECLARE large_data BYTEA; BEGIN large_data := decode(repeat('DEADBEEF', 102400000), 'hex');
RETURN large_data; END; $$ LANGUAGE plpgsql; I Inserted this sample row 112 times INSERT INTO example_table (binary_data) VALUES (generate_large_data()); Checked that table size SELECT pg_size_pretty(pg_total_relation_size('example_table')); The table size was 305MB I added this table to logical replication (and another table called example_table1 that had similar structure and data. I run the following command select * from pg_stat_progress_copy I got that bytes_processed for each of the tables is over 5GB
