Thanks. I have almost missed this.

+      any variable-free expression (subqueries, window functions, aggregate
+      functions, and set-returning functions are not allowed).  The data type

+      corresponding partition key column.

Parititioning value is slimiar to column default expression in
the sense that it appeas within a DDL. The description for
DEFAULT is:

|  The value is any variable-free expression (subqueries and
|  cross-references to other columns in the current table are not
|  allowed)

It actually refuses aggregates, window functions and SRFs but it
is not mentioned.  Whichever we choose, they ought to have the
similar description.

Ok, I'll follow Tom's suggestion but collate is necessarilly
appears in this shape. For example ('a' collate "de_DE") || 'b')
has the collate node under the top ExprOp and we get a complaint
like following with it.

> ERROR:  unrecognized node type: 123

123 is T_CollateExpr. The expression "value" (mmm..) reuires
eval_const_expressions to eliminate CollateExprs.  It requires
assign_expr_collations to retrieve value's collation but we don't
do that since we ignore collation this in this case.


The following results in a strange-looking error.

> =# create table pt1 partition of p for values in (a);
> ERROR:  column "a" does not exist
> LINE 1: create table pt1 partition of p for values in (a);

The p/pt1 actually have a column a.

The following results in similar error and it is wrong, too.

> =# create table pr1 partition of pr for values from (a + 1) to (a + 2);
> ERROR: column "a" does not exist
> LINE 1: create table pr1 partition of pr for values from (a + 1) to ...

Being similar but a bit different, the following command leads to
a SEGV since it creates PARTITION_RANGE_DATUM_VALUE with value =
NULL. Even if it leaves the original node, validateInfiniteBounds
rejects it and aborts.

> =# create table pr1 partition of pr for values from (hoge) to (hige);
(crash)


I fixed this using pre-columnref hook in the attached v3. This
behavles for columnrefs differently than DEFAULT.

The v3-2 does the same thing with DEFAULT. The behevior differs
whether the column exists or not.

> ERROR:  cannot use column referencees in bound value
> ERROR:  column "b" does not exist

I personally think that such similarity between DEFALUT and
partition bound (v3-2) is not required. But inserting the hook
(v3) doesn't look good for me.

regards.
