- switch from "unknown" parameter in text format to a "json" parameter in
binary format (no dependency update required)
- use a lazy bytestring "json" encoder (via updated hasql)
* limited update/delete now works on views with explicit order
* no default order, enforce order presence
* apply row count to ensure limited mutations
* move requiring order to ApiRequest
This is enabled by adding `!inner` to the embedded resource
/projects?select=*,clients!inner(*)&clients.id=eq.12
This behaviour can be enabled by default with the config option
db-embed-default-join='inner'
Which saves the need for specifying `!inner` on every request.
If this is enabled, the previous behavior can be restored
per request by specifying `!left` on the embedded resource.
/projects?select=*,clients!left(*)&clients.id=eq.12`
Tested on M20/02M/M2M relationships, views, RPC.
For POST on RPC, allows:
* passing a json object without using `Prefer: params=single-object`
The function must be defined with a single unnamed json param and
`Content-Type: application/json` must be specified.
* uploading binary to a function
The function must be defined with a single unnamed bytea param and
`Content-Type: application/octet-stream` must be specified.
* uploading raw text to a function
The function must be defined with a single unnamed text param and
`Content-Type: text/plain` must be specified.
BREAKING CHANGE If there's a function "my_func" having a single
unnamed json param and other overloaded pairs(with any number of
params), PostgREST won't be able to resolve a POST request to
"my_func". For solving this, you can name the unnamed json param.
my_func(json) -> my_func(prm json)
The request.spec GUC contains the schema cache structure in json.
It's only available when the root endpoint(/) is requested and when
db-root-spec is not empty.
Also correct db-root-spec to accept a schema.
Now that PgVersion is not part of DbStructure, Config is a more apt
module for it.
Also rename getDbStructure to queryDbStructure. AppState also had a
getDbStructure function for a record field.
