```
Three problems from log and debugging:
1. sql parameters not set
2. sql route to 2 physics tables, but not one
3. rewritten sql with wrong values clause "((?, ?))", it cause syntax error,
it should be "(?, ?)"
### Reason analyze (If you can)
PostgreSQL grammar parsing. Details see following comments
### Steps to reproduce the behavior, such as: SQL to execute, sharding rule
configuration, when exception occur etc.
Run following example, `ShardingPgVarcharJdbcTest` /
`ShardingPgVarcharProxyTest`
### Example codes for reproduce this issue (such as a github link).
