WithContextFunc adds possibility to get request scoped values from the
ctx.Context before logging lines.
WithoutPGXModule disables adding module:pgx to the default logger context.
The shopspring/decimal package provides a NullDecimal struct intended
for use with nullable SQL NUMERICs and numbers. It has Scanner and
Valuer implementations already, but adding it to this package allows
it to be used with the binary encoding as well.
The implementation is very straightforward, but the tests have been made
slightly more complicated. The previous version wasn't testing the
decimal.Decimal cases, and this change adds those as well as new
NullDecimal cases. I've added some logic to the test harness to catch
these as you need to use the Equals method to properly compare Decimals.
Bug was advancing the read pointer by the length of the value even if it
was a NULL value. Since NULL is indicated by a -1 length it actually
decremented the read pointer.
zap.Any falls back to zap.Reflect, but is better for this case, because
it first checks for the types that zap handles specially. For example,
time.Duration, or error, which zap.Reflect will just treat as untyped
int64 or struct objects, but zap.Any is able to detect these types and
print them properly.
Previously, stdlib.RegisterConnConfig would sometimes reuse the same connection
string for different ConnConfig options (specifically, it happened when a connection
was open and then closed, and then a new, different connection was opened). This
behavior interferes with callers that expect that two connections with the same data
source name are connecting to the same backend database in the same way.
This fix updates stdlib.RegisterConnConfig to use an incrementing sequence
counter to uniquify all returned connection strings.
Fixes#947
