      xact abort state in pg_exec_query_dest, we should continue scanning the
      querytree list, on the off chance that one of the later queries in the
      string is COMMIT or ROLLBACK.

      Fix bug noted by Bruce: FETCH in an already-aborted transaction block · 708f82f1
      Tom Lane authored
      would crash, due to premature invocation of SetQuerySnapshot().  Clean
      up problems with handling of multiple queries by splitting
      pg_parse_and_plan into two routines.  The old code would not, for
      example, do the right thing with END; SELECT... submitted in one query
      string when it had been in transaction abort state, because it'd decide
      to skip planning the SELECT before it had executed the END.  New
      arrangement is simpler and doesn't force caller to plan if only
      parse+rewrite is needed.

      Get rid of postgres.c's separate parsing logic for PGDATESTYLE env. · f4657116
      Tom Lane authored
      variable, instead calling same code in variable.c that is used to parse
      SET DATESTYLE.  Fix bug: although backend's startup datestyle had been
      changed to ISO, 'RESET DATESTYLE' and 'SET DATESTYLE TO DEFAULT' didn't
      know about it.  For consistency I have made the latter two reset to the
      PGDATESTYLE-defined initial value, which may not be the same as the
      compiled-in default of ISO.

      Modify elog() logic so that it won't try to longjmp(Warn_restart) before · e1492cc3
      Tom Lane authored
      Warn_restart has been set by the backend main loop.  This means that
      elog(ERROR) or elog(FATAL) in the postmaster or during backend startup
      now have well-defined behavior: proc_exit() rather than coredump.
      In the case of elog() inside the postmaster, I think that proc_exit()
      is probably not enough --- don't we want our child backends to be
      forced to quit too?  But I don't understand Vadim's recent changes in
      this area, so I'll leave it to him to look over and tweak if needed.

      Standardize on MAXPGPATH as the size of a file pathname buffer, · 51f62d50
      Tom Lane authored
      eliminating some wildly inconsistent coding in various parts of the
      system.  I set MAXPGPATH = 1024 in config.h.in.  If anyone is really
      convinced that there ought to be a configure-time test to set the
      value, go right ahead ... but I think it's a waste of time.

      Several changes here, not very related but touching some of the same files. · e812458b
      Tom Lane authored
      * Buffer refcount cleanup (per my "progress report" to pghackers, 9/22).
      * Add links to backend PROC structs to sinval's array of per-backend info,
      and use these links for routines that need to check the state of all
      backends (rather than the slow, complicated search of the ShmemIndex
      hashtable that was used before).  Add databaseOID to PROC structs.
      * Use this to implement an interlock that prevents DESTROY DATABASE of
      a database containing running backends.  (It's a little tricky to prevent
      a concurrently-starting backend from getting in there, since the new
      backend is not able to lock anything at the time it tries to look up
      its database in pg_database.  My solution is to recheck that the DB is
      OK at the end of InitPostgres.  It may not be a 100% solution, but it's
      a lot better than no interlock at all...)
      * In ALTER TABLE RENAME, flush buffers for the relation before doing the
      rename of the physical files, to ensure we don't get failures later from
      mdblindwrt().
      * Update TRUNCATE patch so that it actually compiles against current
      sources :-(.
      You should do "make clean all" after pulling these changes.

      Rip out QueryTreeList structure, root and branch. Querytree · 507a0a2a
      Tom Lane authored
      lists are now plain old garden-variety Lists, allocated with palloc,
      rather than specialized expansible-array data allocated with malloc.
      This substantially simplifies their handling and eliminates several
      sources of memory leakage.
      Several basic types of erroneous queries (syntax error, attempt to
      insert a duplicate key into a unique index) now demonstrably leak
      zero bytes per query.
