The last two buildfarm runs on frogmouth have failed in initdb,
like this:
creating directory d:/mingw-bf/root/HEAD/pgsql.2492/src/test/regress/./tmp_check/data ... ok
creating subdirectories ... ok
selecting default max_connections ... 100
selecting default shared_buffers ... 128MB
selecting dynamic shared memory implementation ... windows
creating configuration files ... ok
creating template1 database in d:/mingw-bf/root/HEAD/pgsql.2492/src/test/regress/./tmp_check/data/base/1 ... FATAL: could not open shared memory segment "Global/PostgreSQL.851401618": Not enough space
child process exited with exit code 1
It shouldn't be failing like that, considering that we just finished
probing for acceptable max_connections and shared_buffers without hitting
any apparent limit. I suppose it's possible that the final shm segment
size is a bit larger than what was tested at the shared_buffer step,
but that doesn't seem very likely to be the explanation. What seems
considerably more probable is that the probe for a shared memory
implementation is screwing up the system state somehow. It may not be
unrelated that this machine was happy before commit d2aecae went in.
regards, tom lane
