I now installed from:
https://github.com/feodor/postgres

and compiled both a 'fast' and a 'debug' server (=with --enable-cassert see [1])

It turns out that the statement does not crash on a server compiled without --enable-cassert.

But a compile with --enable-cassert shows that a bug is still lurking:

testdb=# select 'x'::hstore || ('a=>"1"':: hstore) ;
The connection to the server was lost. Attempting reset: Failed.

TRAP: FailedAssertion("!(value->array.nelems == 1)", File: "hstore_support.c", Line: 896)

Not good.

( please note that the assert is in a different file ('hstore_support.c') from the earlier assert error that I posted )

Thanks,
