Hi,
I've attached a patch to adjust the error message for CREATE STATISTICS
to account for expressions.
Previously, when attempting to create extended statistics on a single column,
the following error is raised.
ERROR: extended statistics require at least 2 columns
However, this message assumed only columns. In reality, an expression on a
single column is also allowed, so two columns are not necessarily required.
Thgis patch updates the message to:
ERROR: extended statistics require at least 2 columns or an expression
