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)
Clarify the difference between arguments and parameters.
Parameters are part of the function definition, arguments are the values
passed to the function.
Also clarify the findProc function comments and error message.
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.
