Thanks. I'll move the patch to Ready for Committer.

Here is a list of items for committers, including only cosmetic changes.

- Comments in recovery.conf.sample needs to be adjusted.
# (The quotes around the value are NOT optional, but the "=" is.)
It seems to be the only description about quotes are not omissible before.
- We might not need to check the result of ParseConfigFp() because
it always raises FATAL on errors.
- We could remove the unused argument "calling_file" in ParseConfigFp().
- I feel "struct name_value_pair" and "ConfigNameValuePair" a bit
redundant names. I'd prefer something like ConfigVariable.
- "fp" might be a better name than FILE *fd. There are 4 usages in xlog.c.

Sure. We will leave them.
