Hello, I have a data source for example in file format(xml,csv ..etc) , i want to use postgresql engine to query select,update,insert using foreign data wrappers(fdw).
question1 --- > is it possible to prepare our own fdw ?. question2 -----> is it possible to seperate postgresql engine and use it on a data source where i will write fdw to connect the postgresql engine and data source ?. question3 -----> In fdw , we need to provide schema of the file , suppose i will get schema of the file in a varaible and how can we use this variable and directly create a link between datasource and postgresql engine ?. question4 -----> is this fdw(foreign data wrapper) good to use in postgresql ,if so did postgresql prepaired any api kind of fdw officially ? Thanks aluka
