Modified files:
	src/bin/pg_dump: common.c pg_dump.c pg_dump.h 

Log message:
	Fix pg_dump to read-lock all tables to be dumped as soon as it's read
	their names from pg_class.  This considerably reduces the window wherein
	someone could DROP or ALTER a table that pg_dump is intending to dump.
	Not a perfect solution, but definitely an improvement.  Per complaints
	from Marc Fournier; patch by Brent Verner with some kibitzing by Tom Lane.
