Log file says "could not create shared memory segment". It also says
that I should change max_connections or shared_buffers.
Error message claims that max_connections is 23, but postgresql.conf
has this listed as 20.
Error message claims that shared_buffers is 300, but postgresql.conf
has this listed as 2400kB.
What the heck is going on here? (no, the lines in the conf file are
not commented out). How do I enforce the conf file entries?
