unable to parse option x-migrations-table-quoted: %w

Error message

unable to parse option x-migrations-table-quoted: %w

What it means

Same validation as the pgx/v5 driver but in database/postgres (lib/pq path): Open parses the x-migrations-table-quoted URL option with strconv.ParseBool and wraps any parse failure with this message. The migration never reaches the database.

Solutions

  1. Set the option to a ParseBool-valid literal: true, false, 1, 0, t, f, T, F, TRUE, FALSE, True, False
  2. Remove the parameter to accept the default (false)
  3. Percent-encode or single-quote the DSN so no spaces/invalid characters sneak into the value
  4. Confirm with the wrapped strconv error which raw string was rejected

Example fix

// before
dsn := "postgres://u:p@host/db?x-migrations-table-quoted=enabled"
// after
dsn := "postgres://u:p@host/db?x-migrations-table-quoted=true"
Defensive patterns

Strategy: validation

Validate before calling

u, _ := url.Parse(dsn)
if v := u.Query().Get("x-migrations-table-quoted"); v != "" {
    if _, err := strconv.ParseBool(v); err != nil {
        return fmt.Errorf("invalid x-migrations-table-quoted %q: %w", v, err)
    }
}

Type guard

func isParseBoolValue(v string) bool {
    _, err := strconv.ParseBool(v)
    return err == nil
}

Try / catch

if err := openMigrations(); err != nil {
    if strings.Contains(err.Error(), "unable to parse option x-migrations-table-quoted") {
        log.Fatalf("use true/false (or 1/0) for x-migrations-table-quoted: %v", err)
    }
    panic(err)
}

Prevention

When it happens

Trigger: postgres.Open (or the registered database/sql driver 'postgres' via sql.Open + migrate) with a URL like postgres://u:p@host/db?x-migrations-table-quoted=enabled or containing whitespace in the value.

Common situations: Hand-editing DSN strings, config templates emitting 'True' with trailing spaces or 'yes', mixing up this option with another library's boolean syntax, URL-encoding issues leaving %20 in the value.
