Er, make that "column name" above, not "table name". Here's an example of
what I was trying to describe:
lx=# CREATE TABLE abc (a char, b char, c char);
CREATE
lx=# CREATE TABLE xyz (x, y, z) AS SELECT * FROM abc;
ERROR: CREATE TABLE/AS SELECT has mismatched column count
lx=# CREATE TABLE xyz (x, y, z) AS SELECT a, b, c FROM abc;
SELECT
You can explicitly provide each column name in the AS SELECT clause, and
that appears to work properly, but supplying a "*" confuses the backend.
Is this as it should be, or is it a known issue?
