PG: test for "simple" query. SET sql is being ignored by compiler, no special treatment for that by PG wire anymore. Sql parser deals with ';' at end of 'create table' queries.

PG: tests for edge cases and protocol violation in Parse message. Support for Text values in numeric parameters.

CUTLASS: WorkerPool implementation. Refactored HTTP server to use external worker pool rather than spinning its own threads.

GRIFFIN: SQL optimiser bug that could crash server thread.

Removed tests for legacy code (it will be deleted soon too, after all parts have been migrated)

GRIFFIN: "case" implementation for strings - in a hurry to support client tomorrow. This only manually tested. Unit tests to follow.

PG: QuestDB query system supports PG-style bind variables '?' alongside named bind variables ':name'

PG: in QuestDB blob size is limited to 64bit signed int. On PostgreSQL wire protocol blob is 32bit. In order to handle querying massive blobs using PostgreSQL approach we need to gracefully fail query that attempts to fetch oversized blob. This commit implements required behaviour

PG: result set can now be split across multiple send buffers. In other words small send buffer can support large result sets.

PG: send flow control is good, we need to test send flow control on every new feature we add though. Next is to send query result using undersized buffer.

PG: non-blocking server, receive flow control, working tests. I still need to test send flow control.

FIX: bugfix Number.appendHex, this was producing single digits for small numbers. Test for straw man WireParser that would allow to stress test network behaviour
