gmake of the code without interruption.
There's also some tidy-up of the MAXPATHLEN stuff based on the assumption that
all supported platforms have MAXPATHLEN defined in <sys/param.h>.
(The only unknowns for the above are AIX and IRIX5.)
And now - JMP_BUF again. Is it enough, folks ?
Fixed again:
cc1: warnings being treated as errors
exc.c: In function 'ExcRaise':
exc.c:187: warning: passing arg 1 of 'Longjmp' from incompatible pointer type
gmake[3]: *** [exc.o] Error 1
cc1: warnings being treated as errors
datum.c: In function `DatumGetSize':
datum.c:57: warning: unsigned value >= 0 is always 1
gmake[3]: *** [datum.o] Error 1
There was:
if (byVal) {
if (len >= 0 && len <= sizeof(Datum)) {
but len has type Size (unsigned int) and so now there is:
if (byVal) {
if (len <= sizeof(Datum)) {
cc1: warnings being treated as errors
exc.c: In function 'ExcRaise':
exc.c:186: warning: passing arg 1 of 'Longjmp' from incompatible pointer type
gmake[3]: *** [exc.o] Error 1
Now we have:
#if defined (JMP_BUF)
longjmp(efp->context, 1);
#else
siglongjmp(efp->context, 1);
#endif
When an acl item is added or updated the new entry is deleted if it has no
permissions and the acl array is shrinked. This is is done by decrementing
the number of items without updating the corresponding array size.
The array with the incorrect size is later read by pg_aclcheck and the entry
count is used to allocate a new array while the array size is used to copy
the old one. This causes a memory corruption and a backend crash.
This happens only to normal user as the administrator bypasses acl checks.

* Wrote max(date) and min(date) aggregates
* Wrote operator "-" for date; date - date yields number of days
difference
* Wrote operator+(date,int) and operator-(date,int); the int is the
number of days. Each operator returns a new date.

In particular, no more compiled-in default for PGDATA or LIBDIR. Commands
that need them need either invocation options or environment variables.
PGPORT default is hardcoded as 5432, but overrideable with options or
environment variables.
Changes:
* Unique index capability works using the syntax 'create unique
index'.
* Duplicate OID's in the system tables are removed. I put
little scripts called 'duplicate_oids' and 'find_oid' in
include/catalog that help to find and remove duplicate OID's.
I also moved 'unused_oids' from backend/catalog to
include/catalog, since it has to be in the same directory
as the include files in order to work.
* The backend tries converting the name of a function or aggregate
to all lowercase if the original name given doesn't work (mostly
for compatibility with ODBC).
* You can 'SELECT NULL' to your heart's content.
* I put my _bt_updateitem fix in instead, which uses
_bt_insertonpg so that even if the new key is so big that
the page has to be split, everything still works.
* All literal references to system catalog OID's have been
replaced with references to define'd constants from the catalog
header files.
* I added a couple of node copy functions. I think this was a
preliminary attempt to get rules to work.
