@MironAtHome Just understand that it wasn't intended nor expected to be used outside of this [security issue] context. So it may not work as expected. And, come to think of it, it may not work in parallel. I need to think about the latter. The general idea behind it was to allow parameters to be passed to the `cypher()` function. The issue being that `cypher($1, $2)` doesn't work due to when parameters `($1, $2)` are resolved (in the execution phase) and when they are needed (in the cypher parse phase which comes before the execution phase). By using `age_prepare_cypher($1, $2)` the parameters are resolved at execution and a global structure for that specific process is set up to contain, for one time only, the graph name and cypher command. The very next command needs to be `cypher(NULL, NULL)`. Any other cypher command will error out and reset it. That next `cypher(NULL, NULL)` will then use those resolved parameters. The structure is then cleared. That is basically how the two commands work together `age_prepare_cypher($1, $2)` then `cypher(NULL, NULL)`. -- This is an automated message from the Apache Git Service.
