Hi I am thinking about simplifying a deployment some multiversion PostgreSQL extensions, and scripts.
With current possibilities, we have to use DO statement, what is not optimal or possible in some use cases. The implementation of condition block (possible nested) is very simple. The proposed syntax of new psql commands \if_ver_eq 9.2 ... \else \endif \if_ver_gt 9.2 \if_ver_ge 9.2 \if_ver_le 9.2 \if_ver_lt 9.2 minor versions can be supported too \if_ver_ge 9.2.0 \endif \if_def psqlvariable \if_eq psqlvariable \if_ne psqlvariable What do you thinking about it? Regards Pavel
