[Bug]: Date filters are not supported for `date` in Postgres

### What happened?

Say if the table has a column type as Date, and we're trying to execute a graphql query like below

```
query {
  todos(filter: { dueDate: { gte: "2024-01-01T00:00:00.000Z" } }) {
    items {
      dueDate
    }
  }
}
```
Then we will hit below error "operator does not exist: date >= text":
```
{
"errors": [
{
"message": "42883: operator does not exist: date >= text\r\n\r\nPOSITION: 168",
"locations": [
{
"line": 2,
"column": 2
}
],
"path": [
"todos"
],
"extensions": {
"code": "DatabaseOperationFailed"
}
}
],
"data": null
}
```

It looks like eventually the SQL statements generated will convert the string literal "2024-01-01T00:00:00.000Z" into Text type in PGSQL, and such comparison is not supported.

I can reproduce the same by running below SQL query directly with PGSQL
