587081a643 postgres: refactor error handling to fix retrying
prior to this change, many of the functions in the ExecTx callback would
wrap the error before returning it. this made it impossible to check
for the error code.

instead, the error wrapping has been moved to be external to the
`ExecTx` callback, so that the error code can be checked and
serialization failures can be retried.

9b9013a560 postgres: use stdlib to set serializable tx level
also use a context for the rollback, which is a bit cleaner since it
only results in one 'defer', rather than N from the loop

fd20b213bb storage: fix postgres timezone handling
Dex's Postgres client currently uses the `timestamp` datatype for
storing times. This lops of timezones with no conversion, causing
times to lose locality information.

We could convert all times to UTC before storing them, but this is
a backward incompatible change for upgrades, since the new version
of dex would still be reading times from the database with no
locality.

Because of this intrinsic issue that current Postgres users don't
save any timezone data, we chose to treat any existing installation
as corrupted and change the datatype used for times to `timestamptz`.
This is a breaking change, but it seems hard to offer an
alternative that's both correct and backward compatible.

Additionally, an internal flag has been added to SQL flavors,
`supportsTimezones`. This allows us to handle SQLite3, which doesn't
support timezones, while still storing timezones in other flavors.
Flavors that don't support timezones are explicitly converted to
UTC.
