 * link
   sends login link for all usernames
 
-Also proxy can expose following services to the external world:
-
-* postgres protocol over TCP -- usual postgres endpoint compatible with usual
-  postgres drivers
-* postgres protocol over WebSockets -- same protocol tunneled over websockets
-  for environments where TCP connection is not available. We have our own
-  implementation of a client that uses node-postgres and tunnels traffic through
-  websockets: https://github.com/neondatabase/serverless
-* SQL over HTTP -- service that accepts POST requests with SQL text over HTTP
-  and responds with JSON-serialised results.
-
-
-## SQL over HTTP
-
-Contrary to the usual postgres proto over TCP and WebSockets using plain
-one-shot HTTP request achieves smaller amortized latencies in edge setups due to
-fewer round trips and an enhanced open connection reuse by the v8 engine. Also
-such endpoint could be used directly without any driver.
-
-To play with it locally one may start proxy over a local postgres installation
-(see end of this page on how to generate certs with openssl):
-
-```
-./target/debug/proxy -c server.crt -k server.key --auth-backend=postgres --auth-endpoint=postgres://stas@127.0.0.1:5432/stas --wss 0.0.0.0:4444
-```
-
-If both postgres and proxy are running you may send a SQL query:
-```json
-curl -k -X POST 'https://proxy.localtest.me:4444/sql' \
-  -H 'Neon-Connection-String: postgres://stas:pass@proxy.localtest.me:4444/postgres' \
-  -H 'Content-Type: application/json' \
-  --data '{
-    "query":"SELECT $1::int[] as arr, $2::jsonb as obj, 42 as num",
-    "params":[ "{{1,2},{\"3\",4}}", {"key":"val", "ikey":4242}]

-    { "dataTypeID": 1007, "name": "arr" },

-        "ikey": 4242,
-        "key": "val"
-      }
-    }
-  ]
-}
-```
-
-
-With the current approach we made the following design decisions:
-
-1. SQL injection protection: We employed the extended query protocol, modifying
-   the rust-postgres driver to send queries in one roundtrip using a text
-   protocol rather than binary, bypassing potential issues like those identified
-   in sfackler/rust-postgres#1030.
-
-2. Postgres type compatibility: As not all postgres types have binary
-   representations (e.g., acl's in pg_class), we adjusted rust-postgres to
-   respond with text protocol, simplifying serialization and fixing queries with
-   text-only types in response.
-
-3. Data type conversion: Considering JSON supports fewer data types than
-   Postgres, we perform conversions where possible, passing all other types as
-   strings. Key conversions include:
-   - postgres int2, int4, float4, float8 -> json number (NaN and Inf remain
-     text)
-   - postgres bool, null, text -> json bool, null, string
-   - postgres array -> json array
-   - postgres json and jsonb -> json object
-
-4. Alignment with node-postgres: To facilitate integration with js libraries,
-   we've matched the response structure of node-postgres, returning command tags
-   and column oids. Command tag capturing was added to the rust-postgres
-   functionality as part of this change.
-
 ## Using SNI-based routing on localhost
 
 Now proxy determines project name from the subdomain, request to the `round-rice-566201.somedomain.tld` will be routed to the project named `round-rice-566201`. Unfortunately, `/etc/hosts` does not support domain wildcards, so I usually use `*.localtest.me` which resolves to `127.0.0.1`. Now we can create self-signed certificate and play with proxy:
