Re: Getting my Database name in a C Extension

I'm writing an extention (FDW), and I need, in my C code, the name of
my database ("contrib_regression_test" for example), and I've two
questions:

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.
