Previously, when a bulk insert operation exceeded the PostgreSQL
protocol's 2GB message size limit, Bun would panic with "integer
does not fit in destination type". This typically occurred with
around 8,150+ items depending on row size.
This change:
- Adds a new specific error.MessageTooLarge to the error set
- Checks message size before casting to i32 in NewWriter.zig
- Returns ERR_POSTGRES_MESSAGE_TOO_LARGE with a clear, actionable message
- Keeps error.Overflow generic for future numeric overflow cases
The error message now clearly explains:
"Query message exceeds PostgreSQL protocol limit of 2GB. Try reducing
the number of rows in your bulk insert or split it into smaller batches."

## Summary
- Fixes binary format handling for PostgreSQL TIME and TIMETZ data types
- Resolves issue where time values were returned as garbled binary data
with null bytes
## Problem
When PostgreSQL returns TIME or TIMETZ columns in binary format, Bun.sql
was not properly converting them from their binary representation
(microseconds since midnight) to readable time strings. This resulted in
corrupted output like `\u0000\u0000\u0000\u0000\u0076` instead of proper
time values like `09:00:00`.
## Solution
Added proper binary format decoding for:
- **TIME (OID 1083)**: Converts 8 bytes of microseconds since midnight
to `HH:MM:SS.ffffff` format
- **TIMETZ (OID 1266)**: Converts 8 bytes of microseconds + 4 bytes of
timezone offset to `HH:MM:SS.ffffff±HH:MM` format
## Changes
- Added binary format handling in `src/sql/postgres/DataCell.zig` for
TIME and TIMETZ types
- Added `InvalidTimeFormat` error to `AnyPostgresError` error set
- Properly formats microseconds with trailing zero removal
- Handles timezone offsets correctly (PostgreSQL uses negative values
for positive UTC offsets)
## Test plan
Added comprehensive tests in `test/js/bun/sql/postgres-time.test.ts`:
- [x] TIME and TIMETZ column values with various formats
- [x] NULL handling
- [x] Array types (TIME[] and TIMETZ[])
- [x] JSONB structures containing time strings
- [x] Verification that no binary/null bytes appear in output
All tests pass locally with PostgreSQL.
