getSymbols.PostgreSQL

[AndreMikulec]

If no symbols are found

for(i in 1:length(Symbols)) {
Browse[2]> 1:length(Symbols)
[1] 1 0

But then this is correct.

Browse[2]> seq_along(Symbols) # REPLACED
integer(0)

I made those changes everywhere in the file.

Adds the function ( with documentation ) getSymbols.PostgreSQL

This very very similar to the getSymbols.MySQL code.

What is more/different follows.

This function can have PostgreSQL tables named MSFT returning symbols and columns MSFT and MSFT.Open. Also, this function can have PostgreSQL tables named msft returning symbols
and columns msft and msft.Open.. This is because PostgreSQL has case-senstive identifier names and an ugly required "NaMe" exists for upper case identifiers to be used SQL strings.
This lowercase-ism is meant as a slight user convenience. I warn users by making a comment in the .Rd that the lower case name msft is not recommended in the quantmod workflow ( I mean to say: so use uppercase PostgreSQL table names like MSFT and ignore the lowecase feature).

Two extra parameters may be passed: options and search_path.

options: is a pass-through to the RPostgreSQL connection.

search_path: allows the user to set a specific search path when looking for PostgreSQL tables.
This is somewhat PostgreSQL specific.

Otherwise, this is the same as the getSymbols.MySQL code.

Please close. I have implemented this elsewhere.
