That rings a bell: "The current rule for this is that the first five executions are done with custom plans[...]" from https://www.postgresql.org/docs/12/sql-prepare.html And your functions create prepared statements under the hood: https://www.postgresql.org/docs/12/plpgsql-implementation.html#PLPGSQL-PLAN-CACHING I guess you should visit https://www.postgresql.org/docs/12/runtime-config-query.html#GUC-PLAN-CACHE_MODE and try if plan_cache_mode = force_custom_plan helps here.
