Re: stale WAL files?

As per your configuration :

max_wal_size = 50GB

this seems to be the cause for the WAL files piling up.

this has been declared twice, the last one is taking effect.

I've manage to generate another 359 WAL files in a 10 minute span yesterday (now only 357 remain and I suspect they will wither away as before).  Are these being held simply because of the high max_wal_size value?

This is a development environment, wherein I'm loading 4M+ records, first into 41 staging tables 100K rows per.  In a loop over each staging table, the data is then placed into application tables via selects. First select * into "matching table" then select id into intersection record (id, fixed groupId).  Each such iteration is in it's own transaction.  I have dropped and recreate this same database numerous times working my way up from 100K to 4M records, dialing in application parameters according to number of primary records.  I have not, however, dropped the last incarnation.
