issues with failure to complete push since implementing PG global statement timeout

[nico599]

Not a direct issue, or bug, more of a question:

Context:
_Due to repeated crashes on a server I was forced to implement a global timeout in Postgres.
Since then Im seeing wal-e FATAL errors: Failed to complete backup-push of /var/lib/pgsql/10

Does anyone know how I might implement a sessional override of the timeout for wal-e?
As its a python process rather than native I can give it the usual override. e.g PGOPTIONS="-c statement_timeout=0"
