It seems that since this commit, JIT statistics are now only being printed for parallel query plans. This is due to ExplainPrintJIT being called before ExecutorEnd, so in a non-parallel query, queryDesc->estate->es_jit_combined_instr will never get set. Attached a patch that instead introduces a new ExplainPrintJITSummary method that summarizes the statistics before they get printed. I've also removed an (I believe) unnecessary "if (estate->es_instrument)" check that prevented EXPLAIN without ANALYZE from showing whether JIT would be used or not. In addition this also updates a missed section in the documentation with the new stats output format. Best, Lukas -- Lukas Fittl
