The following bug has been logged online:
Bug reference: 4933
Logged by: Aaron Marcuse-Kubitza
Email address: aaro...@blackducksoftware.com
PostgreSQL version: 8.3.7
Operating system: Mac OS X 10.5.7
Description: ts_rewrite() causes segfault when query with more than
one node becomes empty
Details:
Running
SELECT ts_rewrite('''example'' & ''example'''::tsquery,
'''example'''::tsquery, ''::tsquery)
causes the error "LOG: server process (PID ...) was terminated by signal
11: Segmentation fault". Any combination of &, |, and () using only
'example' nodes causes the same problem.
However, running
SELECT ts_rewrite('''example'''::tsquery, '''example'''::tsquery,
''::tsquery)
works as expected.
