Please look at the segmentation fault triggered by the following query since
4d969b2f8:
CREATE TABLE t1(a text COMPRESSION pglz);
CREATE TABLE t2(a text);
CREATE TABLE t3() INHERITS(t1, t2);
NOTICE: merging multiple inherited definitions of column "a"
server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
Core was generated by `postgres: law regression [local] CREATE TABLE '.
Program terminated with signal SIGSEGV, Segmentation fault.
