All, I've been installing postgres from source on os x for years, but I haven't generally run 'make check' before I install. I don't feel that running 'make check' is terribly necessary in this case - it's a personal sandbox on my laptop, with no production value. Regardless, I realize that it's beneficial, so I took the extra time today, and ran across this problem. I've got 8_4_STABLE checked out from CVS, and I've run configure as follows: ./configure --with-bonjour --with-python --with-perl Configure completed, and 'make' ran successfully. The relevant output from 'make check' is: ./pg_regress --inputdir=. --dlpath=. --multibyte=SQL_ASCII --load-language=plpgsql --temp-install=./tmp_check --top-builddir=../../.. --schedule=./parallel_schedule ============== creating temporary installation ============== ============== initializing database system ============== pg_regress: initdb failed Examine /Users/thart/projects/pgsql/src/test/regress/log/initdb.log for the reason.

FATAL: could not create shared memory segment: Cannot allocate memory DETAIL: Failed system call was shmget(key=1, size=1613824, 03600). HINT: This error usually means that PostgreSQL's request for a shared memory segment exceeded available memory or swap initdb can and does create a valid database cluster when run by itself, and so far I haven't had any issues with 8.4 during very casual use.
