Look at the PostgreSQL logs and see. It's easier to trace if you set
log_line_prefix to something like:

log_line_prefix = '<a=%a,u=%u,db=%d,pid=%p,vtx=%v,tx=%x,cmd=%i>'

which produces significantly more verbose logs but makes it easier to,
using the pid and txix/vtxid info, work out how different logged
statements fit into transactions.
