x-migrations-table must be quoted (for instance '"migrate"."

Error message

x-migrations-table must be quoted (for instance '"migrate"."schema_migrations"') when x-migrations-table-quoted is enabled, current value is: %s

What it means

golang-migrate requires that when x-migrations-table-quoted=true, the x-migrations-table value must be a fully double-quoted Postgres identifier (starting and ending with "), e.g. "migrate"."schema_migrations". If a migrations table is set but the first or last character is not a quote, Open rejects the URL. This guards against accidentally treating an unquoted identifier as a quoted one.

Solutions

  1. Wrap the migrations table value in double quotes, including the schema if present: x-migrations-table="migrate"."schema_migrations"
  2. Ensure quotes survive URL encoding/shell quoting — use single-quoted shell strings or percent-encode (%22)
  3. Set x-migrations-table-quoted=false if the table name does not need case-sensitivity or special characters
  4. Drop x-migrations-table-quoted entirely when using a plain unquoted table name

Example fix

// before
dsn := "postgres://u:p@host/db?x-migrations-table=migrate.schema_migrations&x-migrations-table-quoted=true"
// after
dsn := `postgres://u:p@host/db?x-migrations-table="migrate"."schema_migrations"&x-migrations-table-quoted=true`
Defensive patterns

Strategy: validation

Validate before calling

u, _ := url.Parse(dsn)
q := u.Query()
tbl := q.Get("x-migrations-table")
if q.Get("x-migrations-table-quoted") == "true" && tbl != "" {
    if !strings.HasPrefix(tbl, `"`) || !strings.HasSuffix(tbl, `"`) {
        return fmt.Errorf("x-migrations-table must be fully quoted, got %q", tbl)
    }
}

Type guard

func isFullyQuotedIdentifier(s string) bool {
    return len(s) >= 2 && strings.HasPrefix(s, `"`) && strings.HasSuffix(s, `"`)
}

Try / catch

if err := migrateOpen(); err != nil {
    if strings.Contains(err.Error(), "x-migrations-table must be quoted") {
        log.Fatalf("wrap x-migrations-table in double quotes: %v", err)
    }
    panic(err)
}

Prevention

When it happens

Trigger: Open with a URL containing both x-migrations-table=schema_migrations and x-migrations-table-quoted=true, where the table value does not start and end with '"', e.g. ?x-migrations-table=migrate.schema_migrations&x-migrations-table-quoted=true.

Common situations: Enabling the quoted flag but forgetting to wrap the table (and optional schema) in double quotes; JSON/YAML/shell layers stripping the quote characters; copy-pasting a plain table name while adding the new quoted option after upgrading golang-migrate.
