Comment (by melvyn-sopacua):
Analysis:
In `django/contrib/postgres/search.py` we find in __init__() around line
55 (stable/1.10.x):
{{{
self.source_expressions = [
Coalesce(expression, Value('')) for expression in
self.source_expressions
]
}}}
These are propagated to Coalesce() and generate the expression:
{{{
COALESCE("entities_show"."cid", '')
}}}
For most cases, the empty string is a valid input value, yet for the
native PostgreSQL UUID type, this is not the case. The API doesn't provide
a way to specify the fallback value.
