Backpatch addition of pump_until() more completely.
Ina2ab9c06ea
I just backpatched the introduction of pump_until(), without changing the existing local definitions (as6da65a3f9a
). The necessary changes seemed more verbose than desirable. However, that leads to warnings, as I failed to realize... Backpatch to all versions containing pump_until() calls beforef74496dd61
(there's none in 10). Discussion: https://postgr.es/m/2808491.1651802860@sss.pgh.pa.us Discussion: https://postgr.es/m/18b37361-b482-b9d8-f30d-6115cd5ce25c@enterprisedb.com Backpatch: 11-14
