This is NOT written into verify.result.</p>
|
||
<p>The prelude is protocol-aware:</p>
|
||
<ul>
|
||
<li><code>CREATE DATABASE</code> is always sent via gRPC so it works regardless of
|
||
statement-level protocol directives.</li>
|
||
<li>For Postgres-protocol statements, <code>SET search_path</code> selects the case
|
||
namespace instead of running <code>USE</code> (which is not valid PG SQL).</li>
|
||
<li>For MySQL and default/gRPC statements, <code>USE <ns></code> runs through the
|
||
statement’s effective context.</li>
|
||
</ul>
