Tables get stuck at srsubstate = f

[Avi Weinberg <AviW@xxxxxxxxx>]

Hi all,

 

I'm using logical replication with Postgres 15.2. 

 

When creating logical replication on multiple tables, sometimes the initial sync get stuck for few tables at state srsubstate = f.  If I recreate the logical replication again, it may get stuck at srsubstate = f  for other tables, so it does not seems to be table specific.  If course, in the majority of cases, building the logical replication succeed and all tables are showing srsubstate = r.   

 

What might be the reason that logical replication get stuck during initial sync at srsubstate =f? 

We use this view pg_stat_progress_copy to monitor initial sync.  Is it possible that calling this frequently during initial sync causes some lock not to be released?

Is it a Postgres bug?

 

Thanks!
