commit 33bf7318f94ce730563eb5ed95ad6c61d6e6f7a6

Make index_concurrently_create_copy more general
Also rename it to index_create_copy. Add a 'boolean concurrent' option,
and make it work for both cases: in concurrent mode, just create the
catalog entries; caller is responsible for the actual building later.
In non-concurrent mode, the index is built right away.
This allows it to be reused for other purposes -- specifically, for
concurrent REPACK.
(With the CONCURRENTLY option, REPACK cannot simply swap the heap file and
rebuild its indexes. Instead, it needs to build a separate set of
indexes, including their system catalog entries, *before* the actual
swap, to reduce the time AccessExclusiveLock needs to be held for. This
approach is different from what CREATE INDEX CONCURRENTLY does.)
Per a suggestion from Mihail Nikalayeu.
