Concurrent use of portals and simple queries invalidates portals #553
Description
To reproduce:
//from CursorTest.scala
sessionTest("invalidation") { s =>
cursor(s).use { c =>
for {
_ <- c.fetch(1)
_ <- s.execute(sql"select 1;".query(int4))
_ <- c.fetch(1)
} yield ()
}
}This will fail with exception Problem: Portal "portal_2" does not exist.
From what is seen on tcpdump and wireshark, Portal get invalidated implicitly and server takes it as a given and not sends any message for its invalidation.
expected behavior:
This is hard to say, as it is exactly what postgres do which is inconvenient IMO, but this is issue can be mitigated by warnings on document, method docs etc.
