URL: https://github.com/apache/datafusion/pull/13194
## Which issue does this PR close?
Part of #4539
## Rationale for this change
In order to support `EXECUTE` for prepared statements, we should first
support creating logical plans for `EXECUTE` statements.
The syntax is same to PostgreSQL.
```
psql=> prepare p(int) as select $1;
PREPARE
psql=> execute p(10);
?column?
----------
10
(1 row)
```
## What changes are included in this PR?
Add a new LogicalPlan
```rust
pub struct Execute {
/// The name of the prepared statement to execute
pub name: String,
/// The execute parameters
pub parameters: Vec<Expr>,
/// Dummy schema
pub schema: DFSchemaRef,
}
```
