Обсуждение: Resolving pg_standby -l

Short patch to
1. disable pg_standby -l
    One line change only appropriate for this stage of release
2. Remove mention of -l and link from docs

pg_standby -l is still accepted, just does nothing (for now).

Existing code maintained in case we backpatch a fix for linking problem
at a later date.

Ah, I had forgotten about this already.

Committed. The patch looks very safe to me, but given that we're just
about to wrap the release I'm keeping my fingers crossed that this
didn't break anything,.

I didn't commit this to the back-branches yet, because I'm not sure if
we have consensus on that. If symlinking has a meaningful performance
advantage, someone might be unhappy if we disable that option in a minor
release. I think we should go ahead anyway, but does anyone object?

Just for future reference: the above is going to look like hell after
pgindent gets its hands on it.  Better style for this project is
/* * ordinary comment block */
#ifdef NOT_USEDcode to be disabled
#endif
