resolves#1584
BREAKING CHANGE:
Changed output of RPCs to match return type better:
* single scalar return: value (unchanged)
* setof scalar return: array of values (new; was array of objects)
* single composite return: object (new; was array of objects)
* setof composite return: array of objects (unchanged)
* void return: nothing (new; was "null")
A single OUT column is now treated as "composite" instead of "scalar",
i.e. consistent with multiple OUT columns.
- Parametrize filters
- Parametrize LIMIT/OFFSET
- Parametrize JSON path(select=col->$1)
- Single parameter for IN(use ANY)
- Also enable prepared statement for the EXPLAIN
used on the estimated count.
Change callProc/createWriteStatement to H.Snippet.
Parametrize the inputs on the same SQLFragments by taking advantage
of hasql-dynamic-statements. It's not necessary to parametrize
every input, inlining with pgFmtLit can still be used for queries
that can't be parametrized(like SET LOCALs).
Also adds hasql-dynamic-statements to Nix and stack.
Improves performance by not utf8 encoding the whole query with
encodeUtf8. Only certain parts.
It's also a gradual step needed to use the Snippet type
from hasql-dynamic-statements.
The good part is that protolude 0.3.0 builds with GHC 8.10.
The bad part is that this change is a bit painful:
- the default `toS` has changed to no longer convert to and from ByteString
- similarly, `show` no longer outputs ByteString
The changes here are pretty much minimal to keep things compiling; I didn't
see a nice way to work with the new ConvertText class, even though `toUtf8`
seems like it might help if used besides `toS` at just the right spots.
The changes here are from fixing stack build with LTS 15.8 (GHC 8.8.3)
to be warning-free. Most if not all come from the newer protolude
version, which adds some things like `unwords`.
So to make sure that we don't get unused import warnings with newer
stackage, this both raises the protolude lower bound and removes
these imports.
PATCH/DELETE can now be done without adding Prefer return=minimal when
the user doesn't have SELECT privileges.
* Also fix PATCH wrong HTTP status code
