[DuckDB] Parsing DuckDB SQL will convert into illegal usage of CURRENT_TIMESTAMP, CURRENT_DATE

[BTheunissen]

It appears that CURRENT_TIMESTAMP/CURRENT_DATE will be transformed into CURRENT_TIMESTAMP()/CURRENT_DATE() which is illegal in DuckDB.

Fully reproducible code snippet

import sqlglot
import duckdb 

ts_sql = "SELECT CURRENT_TIMESTAMP"
date_sql = "SELECT CURRENT_DATE"

ts_res = sqlglot.parse_one(ts_sql, read="duckdb").sql()
date_res = sqlglot.parse_one(date_sql, read="duckdb").sql()

print(ts_res)
print(date_res)

duckdb.execute(ts_sql).fetchall() # Works
duckdb.execute(date_sql).fetchall() # Works
duckdb.execute(ts_res).fetchall() # Doesn't work `Parser Error: syntax error at or near ")"`
duckdb.execute(date_res).fetchall() # Doesn't work `Parser Error: syntax error at or near ")"`
