Hi Team When I am open existing function in database then I am getting this type of error

SQL Error [58P01]: ERROR: could not access file "$libdir/postgis-3": No such file or directory ERROR: could not access file "$libdir/postgis-3": No such file or directory ERROR: could not access file "$libdir/postgis-3": No such file or directory

And My postgres.conf file is here.

-----------------------------

PostgreSQL configuration file

-----------------------------

This file consists of lines of the form:

name = value

(The "=" is optional.) Whitespace may be used. Comments are introduced with

"#" anywhere on a line. The complete list of parameter names and allowed

values can be found in the PostgreSQL documentation.

The commented-out settings shown in this file represent the default values.

Re-commenting a setting is NOT sufficient to revert it to the default value;

you need to reload the server.

This file is read on server startup and when the server receives a SIGHUP

signal. If you edit the file on a running system, you have to SIGHUP the

server for the changes to take effect, run "pg_ctl reload", or execute

"SELECT pg_reload_conf()". Some parameters, which are marked below,

require a server shutdown and restart to take effect.

Any parameter can also be given as a command-line option to the server, e.g.,

"postgres -c log_connections=on". Some parameters can be changed at run time

with the "SET" SQL command.

Memory units: B = bytes Time units: us = microseconds

kB = kilobytes ms = milliseconds

MB = megabytes s = seconds

GB = gigabytes min = minutes

TB = terabytes h = hours

d = days

------------------------------------------------------------------------------

FILE LOCATIONS

------------------------------------------------------------------------------

The default values of these variables are driven from the -D command-line

option or PGDATA environment variable, represented here as ConfigDir.

These options allow settings to be loaded from files other than the

default postgresql.conf. Note that these are directives, not variable

assignments, so they can usefully be given more than once.

include_dir = '...' # include files ending in '.conf' from

                # a directory, e.g., 'conf.d'

include_if_exists = '...' # include file only if it exists

CUSTOMIZED OPTIONS

------------------------------------------------------------------------------

Add settings for extensions here

shared_preload_libraries = 'pg_stat_statements'

Add the following lines:

pg_stat_statements.track = all pg_stat_statements.max = 10000 # Adjust according to your needs pg_stat_statements.save = true # Optionally save statistics across server restarts

Postgresql Function issue. #762

-----------------------------

PostgreSQL configuration file

-----------------------------

This file consists of lines of the form:

name = value

(The "=" is optional.) Whitespace may be used. Comments are introduced with

"#" anywhere on a line. The complete list of parameter names and allowed

values can be found in the PostgreSQL documentation.

The commented-out settings shown in this file represent the default values.

Re-commenting a setting is NOT sufficient to revert it to the default value;

you need to reload the server.

This file is read on server startup and when the server receives a SIGHUP

signal. If you edit the file on a running system, you have to SIGHUP the

server for the changes to take effect, run "pg_ctl reload", or execute

"SELECT pg_reload_conf()". Some parameters, which are marked below,

require a server shutdown and restart to take effect.

Any parameter can also be given as a command-line option to the server, e.g.,

"postgres -c log_connections=on". Some parameters can be changed at run time

with the "SET" SQL command.

Memory units: B = bytes Time units: us = microseconds

kB = kilobytes ms = milliseconds

MB = megabytes s = seconds

GB = gigabytes min = minutes

TB = terabytes h = hours

d = days

------------------------------------------------------------------------------

FILE LOCATIONS

------------------------------------------------------------------------------

The default values of these variables are driven from the -D command-line

option or PGDATA environment variable, represented here as ConfigDir.

data_directory = 'ConfigDir' # use data in another directory

hba_file = 'ConfigDir/pg_hba.conf' # host-based authentication file

ident_file = 'ConfigDir/pg_ident.conf' # ident configuration file

If external_pid_file is not explicitly set, no extra PID file is written.

external_pid_file = '' # write an extra PID file
