BTW, I looked around for .o files with large BSS numbers, and came across
$ size src/interfaces/ecpg/ecpglib/prepare.o
text data bss dec hex filename
4023 4 1048576 1052603 100fbb src/interfaces/ecpg/ecpglib/prepare.o
That megabyte is from a statically allocated statement cache array.
Seems a bit unfriendly to users of ecpglib, given that many apps
would never use the statement cache (AFAICT you have to explicitly
ask for auto-prepare mode to get to that code).
Doesn't look hard to fix though.
regards, tom lane
