postgres in hybrid profile

[lucasborin]

Description of erroneous behaviour

The statement cds watch --profile hybrid binds the Postgres instance, but the CAP read fails due to resource timeout.

CAP database call:

const entries = await cds.db.run(`SELECT * FROM ... LIMIT 10`)

Console (sensitive data hidden):

[odata] - POST /odata/v4/...
[cds] - TimeoutError: ResourceRequest timed out
    at ResourceRequest._fireTimeout (/home/.../node_modules/generic-pool/lib/ResourceRequest.js:62:17)
    at Timeout.bound (/home/.../node_modules/generic-pool/lib/ResourceRequest.js:8:15)
    at listOnTimeout (node:internal/timers:569:17)
    at process.processTimers (node:internal/timers:512:7)

hm, I did the same thing, but on Azure: https://github.com/Azure-Samples/app-service-javascript-sap-cap-quickstart/blob/293b5a4d78c3ccd2ca38440b0b01a19c2ae6f517/src/.cdsrc.json#L26 that worked ootb. → assumption: this might be an issue with CF/destination?

@lucasborin have you been able to solve this problem on your end?

I'm using SAP HANA now, and I was not able to use the postgres in hybrid mode.
