char relkind;
char relpersistence; /* relation persistence */
bool relispopulated; /* relation is populated */
- bool relreplident; /* replica identifier */
+ char relreplident; /* replica identifier */
char *reltablespace; /* relation tablespace */
char *reloptions; /* options specified by WITH (...) */
char *checkoption; /* WITH CHECK OPTION */
