Bug reference: 2291
Logged by: Tim Kordas
Email address: tkordas@greenplum.com
PostgreSQL version: 8.1.3
Operating system: All
Description: int2vectorrecv() and oidvectorrecv() are wrong (SIGBUS)
Details:
During Greenplum's ongoing effort to expand support for postgres datatypes
in Bizgres-MPP; we discovered some issues with int2vectorrecv() and
oidvectorrecv().
int2vectorrecv() and oidvectorrecv() both use DirectFunctionCall3 to call
array_recv().
DirectFunctionCall3() leaves fcinfo->flinfo NULL.
array_recv() uses fcinfo->flinfo.
Calling array_recv() without a valid fcinfo->flinfo results in SIGBUS.
It would be easy to modify array_recv(), but is probably better to fix the
code in int2vectorrecv()/oidvectorrecv() by replacing the call to
DirectFunctionCall3() with direct forwarded call (similar to
int2vectorsend()):
/* leave arg[0] alone, it is correct */
fcinfo->arg[1] = ObjectIdGetDatum(INT2OID);
fcinfo->arg[2] = Int32GetDatum(-1);
result = (int2vector *)array_recv(fcinfo);
the flinfo->f_extra field used will be that passed in by array_recv()'s
caller.
