It looks like OP is reading the first edition from 1986.

Equel is just mentioned as an example in the introduction and the book
doesn't "drag in proprietary database extensions".
Here is the excerpt from the book ("1.4 COUSINS OF THE COMPILER", page
16):
"Preprocessors
Preprocessors produce input to compilers. They may perform the following
functions:
1. ...
2. ...
3. ...
4. Language extensions. These processors attempt to add capabilities to
the language by what amounts to built-in macros. For example, the
language Equel (Stonebraker et al. [1976]) is a database query language
embedded in C. Statements beginning with ## are taken by the
preprocessor to be database-access statements, unrelated to C, and are
translated into procedure calls on routines that perform the database
access."

That's a pretty stupid conclusion.
