bug: reverse mapping for promql is not performed

[ernado]

Having query

EVAL http_server_duration

And metrics

SELECT DISTINCT name FROM metrics_points WHERE name LIKE 'http.%'

http.server.duration_bucket
http.server.duration_count
http.server.duration_max
http.server.duration_min
http.server.duration_sum
http.server.request_content_length
http.server.response_content_length

The rendered query is

SELECT * FROM `metrics_points` WHERE true
	AND toUnixTimestamp64Nano(timestamp) >= 1703685540000000000
	AND toUnixTimestamp64Nano(timestamp) <= 1703686140000000000
AND (
name = 'http_server_duration'
)
ORDER BY timestamp

Points were ingested via gRPC OTLP protocol.
This can be reproduced in dev/local/ch.
