We have in launch_backend.c:
/*
* The following need to be available to the save/restore_backend_variables
* functions. They are marked NON_EXEC_STATIC in their home modules.
*/
extern slock_t *ShmemLock;
extern slock_t *ProcStructLock;
extern PGPROC *AuxiliaryProcs;
extern PMSignalData *PMSignalState;
extern pg_time_t first_syslogger_file_time;
extern struct bkend *ShmemBackendArray;
extern bool redirection_done;
That comment is not completely true: ShmemLock, ShmemBackendArray, and
redirection_done are not in fact NON_EXEC_STATIC. ShmemLock once was,
but was then needed elsewhere. ShmemBackendArray was static inside
postmaster.c before launch_backend.c was created. redirection_done
was never static.
This patch moves the declaration of ShmemLock and redirection_done to
a header file.
ShmemBackendArray gets a NON_EXEC_STATIC. This doesn't make a
difference, since it only exists if EXEC_BACKEND anyway, but it makes
it consistent.
After that, the comment is now correct.
