I'm writing an extention (FDW), and I need, in my C code, the name of

1) What is the easiest way to get that directly in C?
2) Is there a way to get this information in the SQL extension
installation/update scripts (like the @/extschema/@ substitution)?
you could SELECT CURRENT_CATALOG; using the SPI_ functions from your C, or directly in your SQL extension script... this returns the database name (the name is from the sql standard). see
http://www.postgresql.org/docs/current/static/functions-info.html for more info functions like this available in SQL.
