TC_INITSCRIPT can't handle PostgreSQL dollar quoted strings

A simple program like this:

public static void main(String[] args) throws SQLException {
    Properties properties = new Properties();
    properties.setProperty("username", "postgres");
    properties.setProperty("password", "postgres");

    new ContainerDatabaseDriver().connect(
        "jdbc:tc:postgresql:13:///sakila?TC_TMPFS=/testtmpfs:rw&TC_INITSCRIPT=file:c:/temp/dollar-quoted.sql",
        properties
    );
}

Where the dollar-quoted.sql file contains:

CREATE FUNCTION f ()
RETURNS INT
AS $$
BEGIN
    RETURN 1;
END;
$$ LANGUAGE plpgsql;

Fails with this exception:

Exception in thread "main" org.testcontainers.ext.ScriptUtils$UncategorizedScriptException: Failed to execute database script from resource [CREATE FUNCTION f ()

    RETURN 1;

It seems that the logic borrowed from Spring’s ScriptUtils doesn’t handle real world SQL scripts very well? I can think of numerous other issues that aren’t currently supported, including e.g. MySQL’s DELIMITER statement, etc.

Obviously, like many features, this one is an endless one that’s never finished, given how many different SQL script interpreters and preprocessors there are… I get your arguments here. But people would probably love running their pg_dump generated scripts too…

Also stumbled upon this today. It would be great it stored procedures/functions would support DELIMITER in testcontainers!
