BUG #5890: malloc error
The following bug has been logged online:
Bug reference: 5890
Logged by: Emmanuel
Email address: tuco@pasteur.fr
PostgreSQL version: 8.4.1
Operating system: Mac OSX 10.6.6
Description: malloc error
Details:
When I type a select query and then push the 'tab' key for table name
completion (without) schema name, if there more than one table starting with
the same prefix, I get this error:
legiobiblio=# select pmid from pub<tab>
psql(41402) malloc: *** error for object 0x4: pointer being freed was not
allocated
*** set a breakpoint in malloc_error_break to debug
Abort trap
I have more than one table starting with 'pub...'
- publications
- pub_genes
- pub_org
- pub_auths
However if I precise the schema name like 'public.pub..' and press 'tab'
key, then I get list of table matching the beginning of my table name:
legiobiblio=# select pmid from public.pub<tab>
public.pub_auths public.pub_genes public.pub_org
public.publications
legiobiblio=# select pmid from public.pub
hope my message is clear enough.
Cheers

This is a known and oft-reported bug in OS X's libedit --- it stomps on
memory that doesn't belong to it anytime the number of possible
completions is exactly 9 + 10*N, for any N>=0. Complain to Apple:
the fix was applied upstream quite some time ago, and they are being
derelict by not adopting it. In the meantime, you might consider
building psql with readline instead of libedit. (Note you need real GNU
readline, as /usr/lib/libreadline.dylib is just a link to libedit.)
