It worked for me in a quick test here: issue CREATE INDEX command,
"kill -9" the psql client from another window, wait for indexing to
finish.
I wonder whether you had started a transaction block, viz
begin;
create index ...;
<<kill client>>
Without a commit to match the begin, the index would be discarded.
Another likely prospect is that the CREATE INDEX command actually failed
(ran out of disk space, for example). Did you look in the postmaster
log to see if any error message was recorded?
