OK, I set "log_statement = "all"" The log grew to 1GB in ~minute! It is dominated by this one statement, which occurs every ~1.4 sec: "update WS_BUNDLE set BUNDLE_DATA = $1 where NODE_ID_HI = $2 and NODE_ID_LO = $3" parameter $1 is hex, over 6million characters long !! Surely this is the root of my problem.
It definitely is. Every time you update, you are creating a dead tuple (unless it is HOT capable). If autovacuum can't come in behind and clean that up due to idle in transaction, you are going to have serious problems.
