Subject: [PATCHES] Three small patches. Hi, Here are 3 small patches to the postgreSQL source sup'd on the 6th May 1997. The 1st 2 fix the shell backslash "c" handling used to suppress the newline on some unix shells. (The \c needs to be inside quote.) The 3rd may or may not be the correct way to fix the missing define of INDEX_MAX_KEYS in pg_dump.h
