is a mathematical function that returns the remainder from division of the first argument (the dividend) by the second argument (the divisor).
In PostgreSQL, width_bucket()
is a mathematical function that assigns values to buckets (individual segments) in an equiwidth histogram.
The return type is int.

function to convert a timestamp to another timezone.
According to the PostgreSQL documentation, there are two functions called to_timestamp()
:
More specifically, each function converts the value to a timestamp with time zone value.
Although the Postgres documentation presents them as two separate to_timestamp()
functions, I present them as if they’re one function that accepts either one argument, or two.
In PostgreSQL, you can use the to_date()
function to convert a string to a date.
In PostgreSQL, the current_timestamp()
function returns the current date and time, including the time zone offset.
The timestamp returned is based on the start time of the current transaction.
