Hi. We have a DB server running on a VM hosted on Proxmox (ZFS). We recently
upgraded from PG10 to PG16 and noticed an increase in load and, most
importantly, **uncontrolled** RAM usage growth.

Are you running with or without JIT?


 Hi. Yes, JIT is enabled:
^                    name ^   value ^
 |                     jit |      on |
 |          jit_above_cost |  100000 |
 |   jit_debugging_support |     off |
 |        jit_dump_bitcode |     off |
 |         jit_expressions |      on |
 |   jit_inline_above_cost |  500000 |
 | jit_optimize_above_cost |  500000 |
 |   jit_profiling_support |     off |
