The point is that the command will do a bibfile search when it is not

"Not on a crossref macro argument".
If I take your example and put point on the optional argument [45] and
hit `C-c &', RefTeX says:
No BibTeX entry with citation key \cite[45]
which makes sense.
Besides, one does not even need to call it to get the spurious echo
of
"no such database entry", by just leaving point on a
prenote/postnote.
True. You can disable this by setting the variable
`reftex-auto-view-crossref':
I know, Arash... I like `reftex-auto-view-crossref' and enable it, but
the problem is not with the intended behavior, but with the not useful
and annoying echo which comes when point is idle *outside* a key
argument, if it happens to be in a pre/postnote. And why should
`reftex-view-crossref' behave differently when point is between "4" and
"5", in the MWE, and when it is in the following line, outside the
citation macro altogether? Why run `reftex-view-cr-cite' when we
already know we are not in a citation key, but in a postnote?
To be very explicit, the command in question is `reftex-view-crossref`,
and it is also called by `reftex-view-crossref-when-idle' which is
responsible for the echo message. `reftex-view-crossref` checks if
point is within a macro with `(car (reftex-what-macro-safe 1))', and
later checks if it is a citation macro with `(string-match
"\\`\\\\cite\\|cite\\([s*]\\|texts?\\)?\\'\\|bibentry" macro)'. My
suggestion is just to add a further check to see if we are indeed in a
mandatory argument (a citation key).
Best,
Gustavo.
