I have a psql script relying on variables passed in on the command line with -v.
Is there any way to assign a default value in case the -v option is forgotten?
Here is an example with pgtap:
select diag('should be printed only in verbose mode') where :testverbose;
This can be called with -v testverbose=true or -v testverbose=false. However, if the assignment is forgotten, it breaks. I'd like to behave it as if testverbose=false was passed.
Currently there is not any scripting functionality in psql. In patch pool is the basic scripting in psql support patch \if, \else \endif - and then you can do it. But not now.
