# tables-proxy-2
Minimal Go project scaffold.
## Prerequisites
- Go 1.22+ installed
## Run
```bash
go run .
```
## Build
```bash
go build .
```
## Notes
- Uses `pgx` stdlib driver. If you're behind PgBouncer (transaction pooling), the DSN includes `prefer_simple_protocol=true` to avoid prepared statements.
