Package: postgresql-8.4
Version: 8.4.7-1
Severity: minor
The altered command line text, as kept in /proc/#/cmdline,
is patched by a large number of NUL characters for each
of the spawned processes: writer, wal-writer, autovacuum
launcher, and stats collector. A typical case is this:
$ hexdump -C /proc/2324/cmdline
00000000 70 6f 73 74 67 72 65 73 3a 20 77 72 69 74 65 72 |postgres: writer|
00000010 20 70 72 6f 63 65 73 73 20 20 20 00 00 00 00 00 | process .....|
00000020 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................|
*
00000070
The master process is correctly ending after a single NUL character.
Presently, the rewritten commandlines will produce irritating artifacts
even when issuing
$ ps ax | grep postgres
Could the strings be shortened at creation time?
Best regards,
Mats Erik Andersson, DM

Oh, I thought these were actual spaces. On a closer look, I think this
is actually a "ps" deficiency for displaying the NUL bytes as spaces.
On my desktop these are not shown anymore, so they seem to have fixed
it. Closing, thanks!
