These two tab completion pieces look strange to me:
/* If we have CREATE|UNIQUE INDEX <sth> CONCURRENTLY, then add "ON" */ else if ((pg_strcasecmp(prev3_wd, "INDEX")
==0 || pg_strcasecmp(prev2_wd, "INDEX") == 0) && pg_strcasecmp(prev_wd, "CONCURRENTLY") == 0)
COMPLETE_WITH_CONST("ON"); /* If we have CREATE|UNIQUE INDEX <sth>, then add "ON" or "CONCURRENTLY" */ else
if((pg_strcasecmp(prev3_wd, "CREATE") == 0 || pg_strcasecmp(prev3_wd, "UNIQUE") == 0) &&
pg_strcasecmp(prev2_wd,"INDEX") == 0) { static const char *const list_CREATE_INDEX[] = {"CONCURRENTLY",
"ON",NULL};
COMPLETE_WITH_LIST(list_CREATE_INDEX); }
They appear to support a syntax along the lines of
CREATE INDEX name CONCURRENTLY
which is not the actual syntax.
